AsmParser/X86: Add temporary hack to allow parsing "sal". Eventually we need

AsmMatcherEmitter: Use stable_sort when reordering instructions, so that order

Added another version of the X86 assembler matcher test case.
This test case is different subset of the full auto generated test case, and a
larger subset that is in x86_32-bit.s (that set will encode correctly).  These
instructions can pass though llvm-mc as it were a logical cat(1) and then
reassemble to the same instruction.  It is useful as we bring up the parser and
matcher so we don't break things that currently work.

Add an option to GVN to remove all partially redundant loads.  This is currently
disabled by default.  This divides the existing load PRE code into 2 phases:
first it checks that it is safe to move the load to each of the predecessors
where it is unavailable, and then if it is safe, the code is changed to move
the load.  Radar 7571861.

Fix typo "of" -> "or" and change the way a line was formatted to fit
into 80 columns to match my artistic preferences.

cleanups.

fix PR6197 - infinite recursion in ipsccp due to block addresses

evaluateICmpRelation wasn't handling blockaddress.

Fixed a couple of optimization with EXTRACT_VECTOR_ELT that assumes the result
type is the same as the element type of the vector.  EXTRACT_VECTOR_ELT can
be used to extended the width of an integer type.  This fixes a bug for
Generic/vector-casts.ll on a ppc750.

Update this test for a trivial register allocation difference.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94989 91177308-0d34-0410-b5e6-96231b3b80d8

Generalize target-independent folding rules for sizeof to handle more
cases, and implement target-independent folding rules for alignof and
offsetof. Also, reassociate reassociative operators when it leads to
more folding.

Generalize ScalarEvolution's isOffsetOf to recognize offsetof on
arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr
to getOffsetOfExpr, for consistency with analagous ConstantExpr routines.

Make the target-dependent folder promote GEP array indices to
pointer-sized integers, to make implicit casting explicit and exposed
to subsequent folding.

And add a bunch of testcases for this new functionality, and a bunch
of related existing functionality.

fix rdar://7590304, a miscompilation of objc apps on arm.  The caller
of objc message send was getting marked arm_apcscc, but the prototype
isn't.  This is fine at runtime because objcmsgsend is implemented in
assembly.  Only turn a mismatched caller and callee into 'unreachable'
if the callee is a definition.

fix rdar://7590304, an infinite loop in instcombine.  In the invoke
case, instcombine can't zap the invoke for fear of changing the CFG.
However, we have to do something to prevent the next iteration of
instcombine from inserting another store -> undef before the invoke
thereby getting into infinite iteration between dead store elim and
store insertion.

Just zap the callee to null, which will prevent the next iteration
from doing anything.

Fix pr6198 by moving the isSized() check to an outer conditional.
The testcase from pr6198 does not crash for me -- I don't know what's up with
that -- so I'm not adding it to the tests.

Add a generalized form of ConstantExpr::getOffsetOf which works for
array types as well as struct types, and which accepts arbitrary
Constant indicies.

MulOp is actually a Mips specific node, so do the match using Opcode. This fixes PR6192

Add an immutable interval map, prepared to be used by flat memory model

Whoops, left some debugging code in that broke
a buildbot.  Removed.

Added the enhanced disassembly library's implementation and
fleshed out the .exports file.  I still have to fix several
details of operand parsing, but the basic functionality is
there and usable.

Simplify code. We can compare TNew with T in one batch.
