Eric Christopher 7990df1ae2 Rework builtin handling and call setup. The builtin handling 
now takes a libcall operand, sets up the arguments correctly and
handles stack adjustments.

Owen Anderson 9c93fd5598 Weight loop unrolling counts by nesting depth. Unrolling deeply nested loops tends to cause high 
register pressure and thus excess spills, which we don't currently recover from well.  This should
be re-evaluated in the future if our ability to generate good spills/splits improves.

Partial fix for <rdar://problem/7635585>.

Jim Grosbach 175d6411c8 Enable the MC-ized ARM asm printer. Passing all local tests, so it's time to 
enable it for real. Leaving the CL option in place to it's easy to disable it
again if (when) testers find something I've missed.

Jakob Stoklund Olesen 1083573796 Don't try to constant fold libm functions with non-finite arguments. 
Usually we wouldn't do this anyway because llvm_fenv_testexcept would return an
exception, but we have seen some cases where neither errno nor fenv detect an
exception on arm-linux.

Jakob Stoklund Olesen 415a7a6fec Revert "Disable codegen prepare critical edge splitting. Machine instruction passes now" 
This reverts revision 114633. It was breaking llvm-gcc-i386-linux-selfhost.

It seems there is a downstream bug that is exposed by
-cgp-critical-edge-splitting=0. When that bug is fixed, this patch can go back
in.

Note that the changes to tailcallfp2.ll are not reverted. They were good are
required.

Rafael Espindola 69aa15155f Odd additional stub framework for the ARM MC ELF emission. 
llc now recognizes the "intent" to support MC/obj emission for ARM, but
given that they are all stubs, it asserts on --filetype=obj --march=arm

Chris Lattner ff0062af62 Fix rdar://8468087 - llvm-mc commutes fmul (and friend) operands. 
My previous fix for rdar://8456371 should only apply to fmulp/faddp,
not to fmul/fadd.  Instruction set orthogonality is overrated or 
something.
