Change the X86 asmprinter to use the mangler to apply suffixes like "$non_lazy_ptr"
...
to symbols instead of doing it with "printSuffixedName". This gets us to the point
where there is a real separation between computing a symbol name and printing it,
something I need for MC printer stuff.
This patch also fixes a corner case bug where unnamed private globals wouldn't get
the private label prefix.
Next up, rename all uses of getValueName -> getMangledName for better greppability,
and then tackle the ppc/arm backends to eliminate "printSuffixedName".

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.

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.

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.

need this anymore now that llvm ir doesn't have type planes.
