Remove ImplicitBadDivides/ExplicitBadDivides node sets.  This checking is now down by a 'Checker' and not build into GRExprEngine.

The patterns will stay blank because ADD reg, reg

useful for the disassembler.

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eventually be superseded by mdefs.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.
