Daniel Dunbar cd01ed5bd6 ADT/Triple: Renambe isOSX... methods to isMacOSX for consistency with the OS 
triple component.

Daniel Dunbar 4a7783b0c2 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 a83b177035 Put each personality function in a section. This fixes the gnu ld warning: 
error in foo.o; no .eh_frame_hdr table will be created.

Rafael Espindola 601a11edd4 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.

Rafael Espindola 70d8015063 Switch llvm to using comdats. For now always use groups with a single 
section.

Rafael Espindola 4b7b7fba38 Delay the creation of eh_frame so that the user can change the defaults. 
Add support for SHT_X86_64_UNWIND.

Rafael Espindola 56eb741237 Initial support for the cfi directives. This is just enough to get 
f:
        .cfi_startproc
        nop
        .cfi_endproc

assembled (on ELF).

Rafael Espindola 9bb44a5ce8 Fixed version of 118639 with an extra assert to catch similar problems 
earlier. Implicit bool -> int conversions are evil!

Michael J. Spencer 0f83d96852 COFF: Add IMAGE_SCN_MEM_READ to text sections. 
There are currently 100 references to COFF::IMAGE_SCN in 6 files
and 11 different functions. Section to attribute mapping really
needs to happen in one place to avoid problems like this.

NAKAMURA Takumi 392f084f46 lib/CodeGen/TargetLoweringObjectFileImpl.cpp: Tweak to emit ".{section}${name}" instead of ".{section}$linkonce_{name}" for linkonce sections. 
It seems GNU ld/PECOFF relies on section names, linking with g++'s libstdc++.a would fail.

Anton Korobeynikov fc3642b205 Do not check that the bodies of two defs of same linkonce global are the same. 
Such a check does not make any sense in presense of inlining and other compiler-dependent stuff.
This should fix bunch of warnings on mingw32.

Bill Wendling d848beb1e5 Fix a FIXME. _foo.eh symbols are currently always exported so that the linker 
knows about them. This is not necessary on 10.6 and later.

Chris Lattner 9f06f911d1 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.
