now that loop passes don't use DomFrontier, there is no reason
...
for the unroller to pretend it supports updating it. It still
has a horrible hack for DomTree.

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.

Experiments show that we can safely increase our unrolling threshold without unduly impacting code size, particularly
...
since unrolling is not enabled at -Os.

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.
