7bd4b77e30 Preparation step for some cleanup/generalization in EH information emission:
provide TAI hook for selection of EH data emission format. Currently unused.

fdd4b3846f Emit unused EH frames for weak definitions on Darwin,
because assembler/linker can't cope with weak absolutes.

3e409a37ac Setting GlobalDirective in TargetAsmInfo by default rather than
providing a misleading facility. It's used once in the MIPS backend
and hardcoded as "\t.globl\t" everywhere else.

50747737a5 TargetAsmInfo::getAddressSize() was incorrect for x86-64 and 64-bit targets
other than PPC64. Instead of fixing it, just remove it and fix all the
places that use it to use TargetData::getPointerSize() instead, as there
aren't very many. Most of the references were in DwarfWriter.cpp.

3c6a8b2814 The personality function on Darwin needs a global stub. We then refer to
that global stub instead of doing the ".set" thingy we were doing before.

2509765bef * Fix one more bug in PIC codegen: extra load is needed for *all*
non-statics.
* Introduce new option to output zero-initialized data to .bss section.
This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.

cfdd717db5 Fix for PR1095:
LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound
inline asm expression.
