[x86] promote 'add nsw' to a wider type to allow more combines

The motivation for this patch starts with PR20134:

void foo(int *a, int i) {
  a[i] = a[i+1] + a[i+2];

It seems better to produce this (14 bytes):

movslq %esi, %rsi
movl 0x4(%rdi,%rsi,4), %eax
addl 0x8(%rdi,%rsi,4), %eax
movl %eax, (%rdi,%rsi,4)

Rather than this (22 bytes):

leal 0x1(%rsi), %eax
leal 0x2(%rsi), %ecx
movslq %ecx, %rcx
movl (%rdi,%rcx,4), %ecx
addl (%rdi,%rax,4), %ecx
movslq %esi, %rax
movl %ecx, (%rdi,%rax,4)

The most basic problem (the first test case in the patch combines constants) should also be fixed in InstCombine,
but it gets more complicated after that because we need to consider architecture and micro-architecture. For
example, AArch64 may not see any benefit from the more general transform because the ISA solves the sexting in
hardware. Some x86 chips may not want to replace 2 ADD insts with 1 LEA, and there's an attribute for that:
FeatureSlowLEA. But I suspect that doesn't go far enough or maybe it's not getting used when it should; I'm
also not sure if FeatureSlowLEA should also mean "slow complex addressing mode".

I see no perf differences on test-suite with this change running on AMD Jaguar, but I see small code size
improvements when building clang and the LLVM tools with the patched compiler.

A more general solution to the sext(add nsw(x, C)) problem that works for multiple targets is available
in CodeGenPrepare, but it may take quite a bit more work to get that to fire on all of the test cases that
this patch takes care of.

Sample profiles - Re-arrange binary format to emit head samples only on top functions.

The number of samples collected at the head of a function only make
sense for top-level functions (i.e., those actually called as opposed to
being inlined inside another).

Head samples essentially count the time spent inside the function's
prologue.  This clearly doesn't make sense for inlined functions, so we
were always emitting 0 in those.

This is a follow-up to the discussion in D12882.

Ideally, we would like SimplifyCFG to be able to form select instructions even when the operands
are expensive (as defined by the TTI cost model) because that may expose further optimizations.
However, we would then like a later pass like CodeGenPrepare to undo that transformation if the
target would likely benefit from not speculatively executing an expensive op (this patch).

Once we have this safety mechanism in place, we can adjust SimplifyCFG to restore its
select-formation behavior that changed with r248439.

Sometimes you want to install a custom compiler and use it like the system compiler without overriding the system compiler. This patch lets you create xctoolchains that the darwin command line tools can use.

To use this patch set LLVM_CREATE_XCODE_TOOLCHAIN=On in your CMake invocation and build the `install-code-toolchain` target.

After installation you can set the envar EXTERNAL_TOOLCHAINS_DIR to your installed Toolchains directory, and the TOOLCHAINS envar to the toolchain identifier (ex org.llvm.3.8.0svn). This will then cause /usr/bin/clang to call your newly installed clang.

x86: preserve flags when folding atomic operations

D4796 taught LLVM to fold some atomic integer operations into a single
instruction. The pattern was unaware that the instructions clobbered
flags. I fixed some of this issue in D13680 but had missed INC/DEC.

Revert 250343 and 250344

Turns out this approach is buggy.  In discussion about follow on work, Sanjoy pointed out that we could be subject to circular logic problems.

 if (i u< L) leave()
 if ((i + 1) u< L) leave()
 print(a[i] + a[i+1])

If we know that L is less than UINT_MAX, we could possible prove (in a control dependent way) that i + 1 does not overflow.  This gives us:
 if (i u< L) leave()
 if ((i +nuw 1) u< L) leave()
 print(a[i] + a[i+1])

If we now do the transform this patch proposed, we end up with:
 if ((i +nuw 1) u< L) leave_appropriately()
 print(a[i] + a[i+1])

That would be a miscompile when i==-1.  The problem here is that the control dependent nuw bits got used to prove something about the first condition.  That's obviously invalid.

This won't happen today, but since I plan to enhance LVI/CVP with exactly that transform at some point in the not too distant future...
