Bill Wendling 087aad44cb Remove a flag that would set the ".eh" symbol as .globl. MachO was the only one 
who used this flag, and it now emits CFI and doesn't emit this anymore. All
other targets left this flag "false".

Rafael Espindola 5426a9ee37 GCC uses a different encoding of pointers in the FDE when using 
-fno-dwarf2-cfi-asm. Implement the same behavior.

Rafael Espindola 7afec9cc0f Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, and 
give it a bit more responsibility. Also implement it for MachO.

If hacked to use cfi, 32 bit MachO will produce

.cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr

and 64 bit will produce

.cfi_presonality ___gxx_personality_v0

The general idea is that .cfi_personality gets passed the final symbol. It is
up to codegen to produce it if using indirect representation (like 32 bit
MachO), but it is up to MC to decide which relocations to create.

Daniel Dunbar 558692fd0a ADT/Triple: Renambe isOSX... methods to isMacOSX for consistency with the OS 
triple component.

Daniel Dunbar ebc5066b9b CodeGen: Eliminate a use of getDarwinMajorNumber(). 
- There is a minor semantic change here (evidenced by the test change) for
   Darwin triples that have no version component. I debated changing the default
   behavior of isOSVersionLT, but decided it made more sense for triples to be
   explicit.

Rafael Espindola 0412d5b40a Fix llvm-gcc bootstrap with gnu ld. 
The problem was codegen guessing the wrong values and printing

	.section	.eh_frame,"aMS",@progbits,4

It is not clear at all if Codegen should try to guess, MC is the
one that should know the default flags.
