Frontend: define _LP64 in a target-independent way
Instead of adding it to each individual subclass in
Targets.cpp, simply check the appropriate target
values.
Where before it was only on x86_64 and ppc64, it's now
also defined on mips64 and nvptx64.
Also add a bunch of negative tests to ensure it is *not*
defined on any other architectures while we're here.
