Douglas Gregor 5fec5b0495 Add basic support for C++ name mangling according to the Itanium C++
ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.

At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.

Nuno Lopes a0abe62904 make ScalarExprEmitter::EmitCompare() emit the expression with the correct type instead of always zext it to an int
this fixes codegen of simple exprs in C++ like 'if (x != 0)'
