c34e1296b8 Add a subtarget hook for reporting the misprediction penalty. Use this to provide more precise 
cost modeling for if-conversion.  Now if only we had a way to estimate the misprediction probability.

Adjsut CodeGen/ARM/ifcvt10.ll.  The pipeline on Cortex-A8 is long enough that it is still profitable
to predicate an ldm, but the shorter pipeline on Cortex-A9 makes it unprofitable.

c0e1200323 Part one of switching to using a more sane heuristic for determining if-conversion profitability. 
Rather than having arbitrary cutoffs, actually try to cost model the conversion.

For now, the constants are tuned to more or less match our existing behavior, but these will be
changed to reflect realistic values as this work proceeds.

now takes a libcall operand, sets up the arguments correctly and
handles stack adjustments.

ffbf83e49f 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.

3e325614db 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

5cadf79b60 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.

0ebcc18dec the latest assembler that runs on powerpc 10.4 machines doesn't 
support aligned comm.  Detect when compiling for 10.4 and don't
emit an alignment for comm.  THis will hopefully fix PR8198.

4fc55c0e02 Revert r114703 and r114702, removing the isConditionalMove flag from instructions. After further
