aac5c915ed Linux also does not require exception handling 
moves in order to get correct debug info.  Since
I can't imagine how any target could possibly
be any different, I've just stripped out the
option: now all the world's like Darwin!

27c38cee90 Darwin doesn't need exception handling information for the "move" info when 
debug information is being output, because it's leet!

f8d5799001 EHPreferredDataFormat hook for PPC targets. Looks like Darwin 
uses the same encoding everywhere. Linux FIXME'ed.

319c7bb405 Fix and enable EH for x86-64 Darwin. Adds 
ShortenEHDataFor64Bits as a not-very-accurate
abstraction to cover all the changes in DwarfWriter.
Some cosmetic changes to Darwin assembly code for
gcc testsuite compatibility.

tests actually care).

f93ea63eaa Enable EH on PPC Darwin. This basically works; there 
are a couple of issues that show up with the optimizer,
but I don't think they're really EH problems.
(llvm-gcc testsuite users note:  By default the testsuite
uses the unwinding code that's built as part of your local
llvm-gcc, which does not work.  You need to trick it into
using the installed system unwinding code to get useful
results.)

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.

770735e1ca Modify emission of jump tables on darwin to emit an extra "l" label that 
delimits the boundaries of jump tables.  This lets the linker's dead code
stripping optimization do a better job.

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.
