relatively expensive comparison analyzer on each instruction. Also rename the
comparison analyzer method to something more in line with what it actually does.
This pass is will eventually be folded into the Machine CSE pass.

form of CMPSD (etc.) Matching a 128-bit memory
operand is wrong, the instruction uses only 64 bits

implementation of the function is equivalent, so no need to provide
the target-specific version until/unless it needs to do something.

Without this what was happening was:
* R3 is not marked as "used"
* ARM backend thinks it has to save it to the stack because of vaarg
* Offset computation correctly ignores it
* Offsets are wrong

This pass tries to remove comparison instructions when possible. For instance,
if you have this code:
sub r1, 1
cmp r1, 0
bz L1
and "sub" either sets the same flag as the "cmp" instruction or could be
converted to set the same flag, then we can eliminate the "cmp" instruction all
together. This is a important for ARM where the ALU instructions could set the
CPSR flag, but need a special suffix ('s') to do so.

register for local access when it's closer to the stack slot being refererenced
than the stack pointer. Make sure to take into account any argument frame
SP adjustments that are in affect at the time.

preserves the existing behavior, as it seems a concious choice to allow RS to
be null and BigStack marked true.

simplify the call frame pseudo instructions. In that situation, the
calculations for estimating the stack size will be way off, leading to
not having an emergency spill slot when we need one. It should be possible
to be more precise about tracking the adjustment values, but not really
necessary for correctness. Upcoming cleanups for PEI in general will
render that moot.

See PR5201. There is no way to know if direct calls will be within the allowed
range for BL. Hence emit all calls as indirect when in JIT mode.
Without this long-running applications will fail to JIT on PowerPC with a
relocation failure.

- The COFF backend doesn't support MingW/Cygwin at the moment, it'll report an
error, but it's still much better than random assertions from the MachO backend.
- We want to make ELF the default eventually, it's what the majority of targets use.

"The CWriter::GetValueName() method does not check if a value as an alias
and emits the alias name which will never be defined in the output .c
file (so the output file fails to compile). This can happen if you have
multiple inheritance with several destructors defined by clang (...D0Ev,
...D1Ev, ...D2Ev)."

Add support for using the FPSCR in conjunction with the vcvtr instruction, for controlling fp to int rounding.
Add support for the FLT_ROUNDS_ node now that the FPSCR is exposed.

After updating your working copy, the first build will fail because it
is using the old library dependencies. Start the build again and it
will work fine.
