3300087d49 indvars: fix a pass-sensitivity issue that would hit the SCEVExpander 
assertion I added in r135333. Check for the existence of a preheader
before expanding a recurrence.

b2c2eec80d Fix SCEVEXpander to handle arbitrary phi expansion. Includes two 
related bug fixes and corresponding assertions for uninitialized data
and missing NULL check. Test cases will be included with the new LFTR.

This should unbreak the build-self-4-mingw32 tester. I have a very
complicated test case that I will try to clean up.

d5b62f3403 Fix a couple of things: 
1) Make non-legal 256-bit loads to be promoted to v4i64. This lets us
canonize the loads and handle things the same way we use to handle
for 128-bit registers. Despite of what one of the removed comments
explained, the load promotion would not mess with VPERM, it's only a
matter of doing the appropriate bitcasts when this instructions comes
to be introduced. Also make LOAD v8i32 legal.

2) Doing 1) exposed two bugs:
- v4i64 was being promoted to itself for several opcodes (introduced
in r124447 by David Greene) causing endless recursion and the stack to
explode.
- there was no support for allOnes BUILD_VECTORs and ANDNP would fail to
match because it was generating early target constant pools during
lowering.

3) The testcases are already checked-in, doing 1) exposed the
bugs in the current testcases.

4) Tidy up code to be more clear and explicit about AVX.

987cd08002 Extract parts of RAGreedy::splitAroundRegion as SplitKit methods. 
This gets rid of some of the gory splitting details in RAGreedy and
makes them available to future SplitKit clients.

Slightly generalize the functionality to support multi-way splitting.
Specifically, SplitEditor::splitLiveThroughBlock() supports switching
between different register intervals in a block.

bdf65ac132 Disable loop idiom recognition of memset/memcpy if the function being compiled 
is named after a common idiom (i.e., memset/memcpy).  Otherwise, we can run into 
infinite recursion.  Ideally, the user should use the correct -fno-builtin flag,
but in case they don't we should play nicely.

57b7a96900 Eliminate "const" from extern const to fix breakeage since r135184 on msvc.

cbac5b4434 Explicitly cast the second argument to unsigned in order to select the

89cfaf4305 Remove an unnecessary header from this file. I don't think this header 
was really intended, and it may have been required prior to some of the
recent refactors. Including it however causes LLVMX86Desc to need
symbols from LLVMX86CodeGen, forming a dependency cycle. This was masked
in almost all builds: Clang, and GCC w/ optimizations didn't actually
emit the symbols!
