Dan Gohman 84117119ff Clang's #include handling apparently doesn't work for libstdc++'s 
fenv.h. See PR6907 for details. Work around this in FEnv.h to fix
the seflhost build.

Jakob Stoklund Olesen 57feeed92f Replace FindLiveRangeContaining() with getVNInfoAt() in LiveIntervalAnalysis. 
This helps hiding the LiveRange class which really should be private.

Michael J. Spencer 43e92d1162 Revert "System: Add SwapByteOrder and update Support/MathExtras.h to use it." 
This reverts commit 116234.

It compiled just fine with MSVC and clang...

map one-to-one with the CodeGenInstruction operand number.

Eric Christopher 71ef1af66b Make sure that the call stack adjustments have default operands. Also 
leave custom lowerings for later.

Jakob Stoklund Olesen 6c4353ecee PowerPC varargs functions store live-in registers on the stack. Make sure we use 
virtual registers for those stores since RegAllocFast requires that each live
physreg only be used once.

This fixes PR8357.

Jim Grosbach 5476a274c8 More binary encoding stuff, taking advantage of the new "by name" operand 
matching in tblgen to do the predicate operand.

Jim Grosbach 191ad7c473 When figuring out which operands match which encoding fields in an instruction, 
try to match them by name first. If there is no by-name match, fall back to
assuming they are in order (this was the previous behavior).

Jakob Stoklund Olesen 2f6531eb8c Properly handle reloading and spilling around partial redefines in 
LocalRewriter.

This is a bit of a hack that adds an implicit use operand to model the
read-modify-write nature of a partial redef. Uses and defs are rewritten in
separate passes, and a single operand would never be processed twice.

Chris Lattner 1ef5e84c31 Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

Chris Lattner eb313a46fc fix the default va_arg expansion (in the realignment case) to not implicitly 
truncate the stack pointer to 32-bits on a 64-bit machine.

Chris Lattner d10babfd65 fix the expansion of va_arg instruction on PPC to know the arg 
alignment for PPC32/64, avoiding some masking operations.

llvm-gcc expands vaarg inline instead of using the instruction
so it has never hit this.
