d402d7374a Here's fun! It turns out that these filter functions can be internal. If they're 
internal, they shouldn't use the indirect pointer stuff. In the case of
throw_rethrow_test, it was marked as 'internal' and calculated its own offset to
its contents.

08e8c98fec Change CommaSeparated processing to do it with StringRef instead of temporary std::strings. 
This requires StringRef'izing ProvideOption which I also did.

folder removes a lot of const_casting and requires no changes to clang or
llvm-gcc.

85478e8cd1 convert a bunch more stuff to use StringRef. The ArgName arguments are now 
stringref because they may not be nul terminated.  For options like -Lfoo
this now avoids a O(n)  temporary std::strings where N is the length of 
the string after -L.

f8d05d7ce6 When computing live intervals for earlyclobber operands, 
we pushed the beginning of the interval back 1, so the
interval would overlap with inputs that die.  We were
also pushing the end of the interval back 1, though,
which means the earlyclobber didn't overlap with other
output operands.  Don't do this.  PR 4964.

6f1a8215c0 The flag "--dot-cfg-only" is at the moment equivalent to the flag "--dot-cfg". 
It prints the content of all bbs, instead of printing empty bbs to make the

this is run after the 'standard function passes', SRoA was

6ddbe2a6ad It's inefficient to have place the exception tables (which contain the LSDA) 
into the __DATA section. At launch time, dyld has to update most of the section
to fix up the type info pointers. It's better to place it into the __TEXT
section and use pc-rel indirect pointer encodings. Similar to the personality
routine.

60739d60bf Make a new X8632_MachoTargetObjectFile TLOF implementation whose 
getSymbolForDwarfGlobalReference is smart enough to know that it 
needs to register the stub it references with MachineModuleInfoMachO,
so that it gets emitted at the end of the file.

Move stub emission from X86ATTAsmPrinter::doFinalization to the
new X86ATTAsmPrinter::EmitEndOfAsmFile asmprinter hook.  The important
thing here is that EmitEndOfAsmFile is called *after* the ehframes are
emitted, so we get all the stubs.

This allows us to remove a gross hack from the asmprinter where it would
"just know" that it needed to output stubs for personality functions.
Now this is all driven from a consistent interface.

The testcase change is just reordering the expected output now that the
stubs come out after the ehframe instead of before.

This also unblocks other changes that Bill wants to make.
