Simplify, NFC.

Switch the driver back to always using clang-cc by default (for C++, and
regardless of the architecture).
 - This is a good default for development & testing; for example without this
   any tests using 'clang' in the test suite will fail on PowerPC, since the
   driver will avoid using clang.

 - We don't want to actually ship something built this way, but that should be
   handled via some sort of configuration file.

We don't need to keep track of the packed alignment, just whether the struct is packed or not. Fixes PR4610.

Move the LLVM field number for bit fields into the BitFieldInfo structure, since it's meaning is completely different than for non-bit fields.

Clean up the ActOnTag action, so that there is only a single entry
point that covers templates and non-templates. This should eliminate
the flood of warnings I introduced yesterday.

Removed the ActOnClassTemplate action, which is no longer used.

Add template specializations to view the call graph in dot format.
