causes the "../foo" to not find the file

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.

Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
fields from MAI: they aren't part of the asm syntax, they are
related to the structure of the object file.

To replace their functionality, add a new 
TLOF::getSymbolForDwarfGlobalReference method which asks targets
to decide how to reference a global from EH in a pc-relative way.

The default implementation just returns the symbol.  The default
darwin implementation references the symbol through an indirect
$non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
handles the weird "foo@GOTPCREL+4" hack.

DwarfException.cpp now uses this to emit the reference to the
symbol in the right way, and this also eliminates another 
horrible hack from DwarfException.cpp:

-    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
-      O << "-" << MAI->getPCSymbol();

llvm-svn: 81991

All of these do not have patterns (they're for the
disassembler).

Many of the floating-point instructions will probably
be rolled into definitions that have patterns, and may
eventually be superseded by mdefs.  So I put them
together and left a comment.

and use PersonalityPrefix/Suffix to achieve the same effect (like
the x86 backend).

This changes the code generated for ppc static mode, but guess what,
we were generating this before:

	.byte	0x9B                                        ; Personality (indirect pcrel sdata4)
	.long	___gxx_personality_v0-.                     ; Personality

which is not correct! (it is not an 'indirect' reference).

VLDM/VSTM instructions, and without this check, the code assumes that an
offset is allowed, as it would be with VLDR/VSTR.  The asm printer,
however, silently drops the offset, producing incorrect code.  Since the
address register in this case is either the stack or frame pointer, the
spill location ends up conflicting with some other stack slot or with
outgoing arguments on the stack.
