60493c3f4f Eliminate PromoteMemoryToRegisterID; just use addPreserved("mem2reg") 
instead, as an example of what this looks like.

9ccaf53ada Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

052f000158 Remove LCSSA's bogus dependence on LoopSimplify and LoopSimplify's bogus 
dependence on DominanceFrontier. Instead, add an explicit DominanceFrontier
pass in StandardPasses.h to ensure that it gets scheduled at the right
time.

Declare that loop unrolling preserves ScalarEvolution, and shuffle some
getAnalysisUsages.

This eliminates one LoopSimplify and one LCCSA run in the standard
compile opts sequence.

it needs to be mapped to refer to the function in the new module, not the old
one. Fixes PR7700.

e84178a0bd Extend SimplifyCFG's common-destination folding heuristic to allow a single 
"bonus" instruction to be speculatively executed.  Add a heuristic to
ensure we're not tripping up out-of-order execution by checking that this bonus
instruction only uses values that were already guaranteed to be available.

This allows us to eliminate the short circuit in (x&1)&&(x&2).

1784d160e4 The hasMemory argument is irrelevant to how the argument 
for an "i" constraint should get lowered; PR 6309.  While
this argument was passed around a lot, this is the only
place it was used, so it goes away from a lot of other
places.

186b3d2606 If a metadata operand is seeded in value map and the metadata should also be seeded in value map. This is not limited to function local metadata. 
Failure to seed metdata in such cases causes troubles when in a cloned module, metadata from a new module refers to values in old module. Usually this results in mysterious bugpoint crashes. For example,
