a342026504 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.

5ad147281a Fix pr4544. When remating, make sure the destination register fits the instruction definition. It may be mismatched due to sub-register coalescing. 
No test case yet because the code doesn't trigger until 75408 is re-applied.

59ecdfbee3 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.

d4f53b373e 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.

16a2c927e9 Move isLCSSAForm, isLoopInvariant, getCanonicalInductionVariable,

in LoopInfo.h or doing tricks.
