rename Memo/Count to AnonGlobalIDs/NextAnonGlobalID to be more
...
descriptive. Thange them to keep track of the ID of a global that is
assigned, not the first mangled name returned for it. Without doing this,
we are required to always use the same suffix for a global that gets
mangled. This means that we can mangle the same global once with $stub
and another time with $non_lazy_ptr or whatever.

Two changes:
...
1) unique globals with the existing "Count" local in Mangler, not with
atomic nonsense. Using atomics will give us nondeterminstic output
from the compiler when using multiple threads, which is bad.
2) Do not mangle an unknown global name with a type suffix. We don't
need this anymore now that llvm ir doesn't have type planes.
