Chris Lattner f34815b32f Change the internal interface to makeNameProper to take a bool that
indicates whether the label is private or not, instead of taking
prefix stuff.  One effect of this is that symbols will be generated
with *just* the private prefix, instead of both the private prefix
*and* the user-label-prefix, but this doesn't matter as long as it
is consistent.  For example we'll now get "Lfoo" instead of "L_foo".
These are just assembler temporary labels anyway, so they never even
make it into the .o file.

Dan Gohman 6f6d864815 Introduce a new LoopInfo utility function makeLoopInvariant, which
works similar to isLoopInvariant, except that it will do trivial
hoisting to try to make the value loop invariant if it isn't already.
This makes it easier for transformation passes to clear trivial
instructions out of the way (the regular LICM pass doesn't run
until relatively late). This is code factored out of LoopSimplify
and other places.

Chris Lattner 105efaf3df 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.

Chris Lattner ec8efcb44e 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.
