Add the `lto_codegen_set_export_dynamic' function.
This function sets the `_exportDynamic' ivar. When that's set, we export all
symbols (e.g. we don't run the internalize pass). This is equivalent to the
`--export-dynamic' linker flag in GNU land:
--export-dynamic
When creating a dynamically linked executable, add all symbols to the dynamic
symbol table. The dynamic symbol table is the set of symbols which are visible
from dynamic objects at run time. If you do not use this option, the dynamic
symbol table will normally contain only those symbols which are referenced by
some dynamic object mentioned in the link. If you use dlopen to load a dynamic
object which needs to refer back to the symbols defined by the program, rather
than some other dynamic object, then you will probably need to use this option
when linking the program itself.
The Darwin linker will support this via the `-export_dynamic' flag. We should
modify clang to support this via the `-rdynamic' flag.

Make the contents of encoded sections SmallVector<char, N> instead of
SmallString. This makes it possible to use the length-erased SmallVectorImpl
in the interface without imposing buffer size. Thus, the size of MCInstFragment

docs: Convert LangRef to reST.
NOTE: If you have any patches in the works that modify LangRef, you will
need to rewrite the changes to LangRef.html to their equivalents in
LangRef.rst. If you need assistance feel free to contact me.
Since LangRef is mission-critical for the project and "normative", I
have taken extra care to ensure that no content was lost or altered in
the conversion. The content was converted with a tool called `pandoc`,
so there is no chance for a human error like accidentally forgetting a
sentence or whatever. After the initial conversion by `pandoc`, only
changes to the markup were done.
This is just the most literal conversion of the HTML document as
possible. It might be worth exploring some way to chop up this massive
document into separate pages, e.g. something like
`docs/LangRef/Instructions.rst`, `docs/LangRef/Intrinsics.rst`, etc.
with `docs/LangRef.rst` being an "intro/navigation page" of sorts. On
the other hand, that loses the ability to {Ctrl,Cmd}-F for a given term
right from your browser.
IMO, I think our stylesheet needs some work because I find it hard to
tell what level of nesting some of the headings are at (e.g. "is this a
new section or is it a subsection?"). The issue is present on other
pages, but the sheer size and deep section structure of LangRef really
brings this issue out. If there are any web designers out there in the
community it would be awesome if you tried to come up with something
nicer.

Add higher-level API for dealing with bundled MachineInstrs.
This is still a work in progress. The purpose is to make bundling and
unbundling operations explicit, and to catch errors where bundles are
broken or created inadvertently.
The old IsInsideBundle flag is replaced by two MI flags: BundledPred
which has the same meaning as IsInsideBundle, and BundledSucc which is
set on instructions that are bundled with a successor. Having two flags
provdes redundancy to detect when a bundle is inadvertently torn by a
splice() or insert(), and it makes it possible to write bundle iterators
that don't need to peek at adjacent instructions.
The new flags can't be manipulated directly (once setIsInsideBundle is
gone). Instead there are MI functions to make and break bundle bonds.
The setIsInsideBundle function will be removed in a future commit. It
should be replaced by bundleWithPred().

Add support to ValueTracking for determining that a pointer is non-null
by virtue of inbounds GEPs that preclude a null pointer.
This is a very common pattern in the code generated by std::vector and
other standard library routines which use allocators that test for null
pervasively. This is one step closer to teaching Clang+LLVM to be able
to produce an empty function for:
void f() {
std::vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
v.push_back(4);
}
Which is related to getting them to completely fold SmallVector
push_back sequences into constants when inlining and other optimizations
make that a possibility.

[msan] Do not store origin for clean values.
Instead of unconditionally storing origin with every application store,
only do this when the shadow of the stored value is != 0.
This change also delays instrumentation of stores until after the walk over
function's instructions, because adding new basic blocks confuses InstVisitor.
We only keep 1 origin value per 4 bytes of application memory. This change
fixes the bug when a store of a single clean byte wiped the origin for the
whole 4-byte area.
Since stores of uninitialized values are relatively uncommon, this change
improves performance of track-origins mode by 5% median and by up to 47% on
specs.

Let targets provide hooks that compute known zero and ones for any_extend
and extload's. If they are implemented as zero-extend, or implicitly
zero-extend, then this can enable more demanded bits optimizations. e.g.
define void @foo(i16* %ptr, i32 %a) nounwind {
entry:
%tmp1 = icmp ult i32 %a, 100
br i1 %tmp1, label %bb1, label %bb2
bb1:
%tmp2 = load i16* %ptr, align 2
br label %bb2
bb2:
%tmp3 = phi i16 [ 0, %entry ], [ %tmp2, %bb1 ]
%cmp = icmp ult i16 %tmp3, 24
br i1 %cmp, label %bb3, label %exit
bb3:
call void @bar() nounwind
br label %exit
exit:
ret void
}
This compiles to the followings before:
push {lr}
mov r2, #0
cmp r1, #99
bhi LBB0_2
@ BB#1: @ %bb1
ldrh r2, [r0]
LBB0_2: @ %bb2
uxth r0, r2
cmp r0, #23
bhi LBB0_4
@ BB#3: @ %bb3
bl _bar
LBB0_4: @ %exit
pop {lr}
bx lr
The uxth is not needed since ldrh implicitly zero-extend the high bits. With
this change it's eliminated.

Add dump of Win64 EH unwind data.
The new command line option -unwind-info dumps the Win64 EH unwind
data to the console. This is a nice feature if you need to debug
generated EH data (e.g. from LLVM). Includes a test case.
Initial patch by João Matos, extensions and rework by Kai Nacke.

Updates to Win64EH.h structures.
Change member types of RuntimeFunction and UnwindInfo from uint64_t to
uint32_t:
These members represent addresses. According to MSDN, they are image
relative, that is, they are 32-bit offsets from the starting address
of the image that contains the function table entry.
See MSDN for more information:
RUNTIME_FUNCTION: http://msdn.microsoft.com/en-us/library/ft9x1kdx.aspx
UNWIND_INFO: http://msdn.microsoft.com/en-us/library/ddssxxy8.aspx
Make Win64.h platform-neutral:
The standard types unit8_t, uint16_t and uint32_t are replaced with
their counterparts from Endian.h. Accessor functions are introduced to
replace bit fields.
Patch by João Matos and Kai Nacke.

Remove the non-const getInst accessor. It wasn't being used, and isn't very
good for enacpsulation anyway.

Adjust JIT target triple on OS X to match the current architecture.
For OS X builds, we generate one version of config.h but then build for
multiple architectures. This means that the LLVM_HOSTTRIPLE setting may have
the wrong architecture. Adjust it dynamically to match the current
architecture. <rdar://problem/

A MachineInstr can only ever be constructed by CreateMachineInstr() and
CloneMachineInstr(), and those factories don't use the removed
