9c33ff8a8b Add a routine to swap branch instruction operands, and update any 
profile metadata at the same time. Use it to preserve metadata attached
to a branch when re-writing it in InstCombine.

Add metadata to the canonicalize_branch InstCombine test, and check that
it is tranformed correctly.

321335142c Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance 
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

0c20486517 Add a bad char heuristic to StringRef::find. 
Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of
uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways.

The worst case is still O(n*m) but we do a lot better on the average case now.

0ef2965563 Fix SCEVExpander assert during LSR: "argument of incompatible type". 
Just because we're dealing with a GEP doesn't mean we can assert the
SCEV has a pointer type. The fix is simply to ignore the SCEV pointer
type, which we really didn't need.

f7ee2603c2 Revert r142046, "Fix for llvm::sys::getHostTriple on Windows. Instead of relying on the triple" 
It extremely breaks builds when optimization is enabled. Twine should not hold temporary objects.

By the way, I might feel sad if I saw "i786-" "i1586-" or "iF86-".

7cc89bde59 Fix indvars randomness by removing iteration over a map. 
I rewrote the algorithm a while back so it doesn't require map lookup,
but neglected to change the data structure. This was caught by
llvm-gcc self host, not because there's anything special about
llvm-gcc, but because it is the only test for nondeterminism we
currently have. Unit tests don't work well for everything; we should
always try to have a nondeterminism stress test running.

Fixes PR11133: llvm-gcc self host .o mismatch after enable-iv-rewrite=false

b0f487f367 Mark tADDrSPi as having side effects again. 
It really doesn't, but when r141929 removed the hasSideEffects flag from
this instruction, it caused miscompilations.  I am guessing that it got
moved across a stack pointer update.

Also clear isRematerializable after checking that this instruction is
in fact never rematerialized in the nightly test suite.
