more than one phi, since that leads to higher register pressure on
entry to the phi. This is especially problematic when the phi is in
a loop header, as it increases register pressure throughout the loop.

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();

A toy for Doug: Add some 'lit' tests which just run clang++ -fsyntax-only over all the files in a directory.
 - 'lit utils/C++Tests' to run, you may need to fix the stdc++ include path, and your mileage may vary.

 - A handful of the LLVM headers are XFAIL because they don't include the right headers.

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eventually be superseded by mdefs.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).

give them the appropriate exception specifications. This,
unfortunately, requires us to maintain and/or implicitly generate
handles to namespace "std" and the class "std::bad_alloc". However,
every other approach I've come up with was more hackish, and this
standard requirement itself is quite the hack.
