Add warning flag -Winvalid-pp-token for preprocessing-tokens which have
undefined behaviour, and move the diagnostic for '' from an Error into
an ExtWarn in this group. This is important for some users of the preprocessor,
and is necessary for gcc compatibility.

Add -ftls-model command-line flag.

This allows for setting the default TLS model. (PR9788)

Don't devirtualize calls when we don't have the correct type of the this pointer
handy. It can be done, but we would have to build a derived-to-base cast
during codegen to compute the correct this pointer.

I will handle covariant returns next.

Disable devirtualization when we have covariant returns. I will open a bug

Warn on weak properties declared in protocols as well.

Previously this caused a crash, since protocols are not interfaces.

Now that we use the GCC builtin <-> llvm intrinsic, dead code eliminate the handwritten emitter.

The generated code uncovered an invalid prototype for __builtin_mips_shilo, fix it along the way.

Dead code eliminate the massive hexagon builtin intrinsic supporting code.

The tablegen'd code does the same thing without this egregious duplication.
In my limited testing everything seems to work, however there can be
differences if the clang and llvm builtin definitions don't match.
