Benjamin Kramer 9c373c1c7a Remove unused variables caught by GCC's -Wunused-but-set-variable.

Eric Christopher d2aa241378 xmm0 is an implicit parameter in this and so shouldn't be in the 
string template.

Fixes rdar://8493866

Dan Gohman 6136e94897 Add an unfolded offset field to LSR's Formula record. This is used to 
model constants which can be added to base registers via add-immediate
instructions which don't require an additional register to materialize
the immediate.

Eric Christopher 39b56b4b9f Apparently the check for direct calls is unnecessary.

Rafael Espindola c2aad4f2a3 Move ppc OS X to cfi too. I am building it on an old ppc mini, but it will take some time.

Rafael Espindola fc8223670a Add r130623 back now that ELF has been fixed to work with -fno-dwarf2-cfi-asm.

Chandler Carruth ddc91b25e3 Remove an unused variable from this function introduced in r130637, 
likely a result of copy/paste.

Rafael Espindola 750cb61553 GCC uses a different encoding of pointers in the FDE when using 
-fno-dwarf2-cfi-asm. Implement the same behavior.

Rafael Espindola fd05785324 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.

Rafael Espindola b7c2286055 Revert the previous patch while I figure out how to make llvm-gcc 
less agressive about disabling cfi on linux :-(

Jakob Stoklund Olesen 2348cdd67f 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.

Rafael Espindola 5265bc483e 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.

Rafael Espindola a3181d12c6 Add all the plumbing needed for MC to expand cfi to the old tables in 
the final assembly. It is the same technique used when targeting
assemblers that don't support .loc.

Eric Christopher 7708746c33 Add FastEmitInst_ii for the arm fast isel generator. It doesn't use it, but 
if it ever did it needs the def machinery.
