4f5de9bb40 Fix X86RegisterInfo::getMatchingSuperRegClass for sub_8bit_hi.
It is OK for B to be any GR8_ABCD_H superclass, the returned register class
doesn't have to map surjectively onto B.

2944b4fe05 Mark ultra-super-registers QQQQ as call-clobbered instead of the D sub-registers.
LiveVariables doesn't understand that clobbering D0 and D1 completely overwrites
Q0, so if Q0 is live-in to a function, its live range will extend beyond a
function call that only clobbers D0 and D1. This shows up in the
ARM/2009-11-01-NeonMoves test case.

LiveVariables should probably implement the much stricter rules for physreg
liveness that RAFast imposes - a physreg is killed by the first use of any
alias.

debd7e4e8b Simplify the handling of pcrel relocations on ELF. Now we do the right thing
for all symbol differences and can drop the old EmitPCRelSymbolValue
method.

This also make getExprForFDESymbol on ELF equal to the one on MachO, and it
can be made non-virtual.

60045c233a X86AsmPrinter doesn't know how to handle the X86II::MO_GOT_ABSOLUTE_ADDRESS flag
after folding ADD32ri to ADD32mi, so don't do that.

This only happens when the greedy register allocator gets itself in trouble and
spills %vreg9 here:

16L             %vreg9<def> = MOVPC32r 0, %ESP<imp-use>; GR32:%vreg9
48L             %vreg9<def> = ADD32ri %vreg9, <es:_GLOBAL_OFFSET_TABLE_>[TF=1], %EFLAGS<imp-def,dead>; GR32:%vreg9

That should never happen, the live range should be split instead.

89fc9e8f5e Enable CFI on OS X.
Currently the output should be almost identical to the one produced by CodeGen
to make the transition easier.

The only two differences I know of are:

* Some files get an extra advance loc of size 0. This will be fixed when
relaxations are enabled.
* The optimization of declaring an EH symbol as an external variable is not
implemented. This is a subset of adding the nounwind attribute, so we if really
this at -O0 we should probably do it at the IL level.
