Summary: Found a couple of cases where unsigned was still being used. These two should be the last ones in the (entire) Mips backend.

We must constrain the destination register class of legalized operands
to a VGPR class or else the illegal operand may be folded back into
the instruction by the register coalescer.
This fixes a bug in add.ll that will be uncovered by future commits.

This patch adds support for the 32bit numeric max/min and directed round-to-integral NEON intrinsics that were added as part of v8, along with unit tests.
Patch by Graham Hunter!

shuffle lowering for integer vectors and share it from v4i32, v8i16, and
v16i8 code paths.
Ironically, the SSE2 v16i8 code for this is now better than the SSSE3!
=] Will have to fix the SSSE3 code next to just using a single pshufb.

Before:
e&& e.SomeFunction();
After:
e && e.SomeFunction();
Yeah, this might be useful for C++, too, but it is not such a frequent
pattern there (plus the fix is much harder).

The special case did not work when run under -reassociate and can easily
be expressed by a further generalization of an existing pattern.

The header contains an offset to the DWARF line table for the CU. The offset
must be section relative for COFF and absolute for others. The non-assembly
code path for the DWARF header generation already has the correct emission for
the headers. This corrects the assembly input path.
This was identified by BFD objecting to the LLVM generated DWARF information.

Patched by Sergey Dmitrouk.
This pass tries to make consecutive compares of values use same operands to
allow CSE pass to remove duplicated instructions. For this it analyzes
branches and adjusts comparisons with immediate values by converting:
GE -> GT
GT -> GE
LT -> LE
LE -> LT
and adjusting immediate values appropriately. It basically corrects two
immediate values towards each other to make them equal.

If we are creating a PE+ executable, we need to run cvtres with
/machine:x64 instead of /machine:x86. Otherwise the resulting executable
would be invalid.

use __thiscall. (This doesn't actually work for MSVC; they don't allow the
__thiscall qualifier here, but it's sufficient to demonstrate that we do
implement the intent of the DR.)

Originally, self reference checking made a double pass over some expressions
to handle reference type checking. Now, allow HandleValue to also check
reference types, and fallback to Visit for unhandled expressions.
