7941350101 Fix PR10387.
When trying to rematerialize a value before an instruction that has an
early-clobber redefine of the virtual register, make sure to look up the
correct value number.

Early-clobber defs are moved one slot back, so getBaseIndex is needed to
find the used value number.

Bugpoint was unable to reduce the test case for this, see PR10388.

2341a3c331 Fix CMake build on Solaris
When building LLVM/Clang on Solaris. The generated makefiles would
have an extraneous semi-colon character in them prior to this change
due to the way the 'CMAKE_CXX_FLAGS' variable was defined. Simply
adjusting the definition by moving the current CMAKE_CXX_FLAGS value
within the quotes solves the problem.

Patch by Art Haas!

5bc37dd131 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.

b4ddedce59 Extract parts of RAGreedy::splitAroundRegion as SplitKit methods.

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