cbda0e255d Add 148175 back. I am unable to reproduce any non determinism in a dragonegg 
or clang bootstrap.

I will keep an eye on the bots.

Original message:
Only emit the Leh_func_endN symbol when needed.

90212bde1f Speculatively revert commit 148175 (rafael), to see if this fixes 
non-determinism in the 32 bit dragonegg buildbot.  Original commit
message:
Only emit the Leh_func_endN symbol when needed.

76792992d6 Add MCObjectFileInfo and sink the MCSections initialization code from 
TargetLoweringObjectFileImpl down to MCObjectFileInfo.

TargetAsmInfo is done to one last method. It's *almost* gone!

fdc3e6fab6 Use .cfi_sections to put the unwind info in .debug_frame when possible. With 
this clang will use .debug_frame in, for example,
clang -g -c -m32 test.c
This matches gcc's behaviour. It looks like .debug_frame is a bit bigger
than .eh_frame, but has the big advantage of not being allocated.

08704349da 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.

a01cdb0e37 Add 129518 back with a fix for when we are producing eh just because of debug info. 
Change ELF systems to use CFI for producing the EH tables. This reduces the
size of the clang binary in Debug builds from 690MB to 679MB.
