Also move 'default' case next to a real case to help compiler optimize in
non-Debug builds.
No functionality change.

Further clean up the comparison function by removing overly generalized
"domains".
Remove all understanding of ELF aliases and simplify folding code and comments.

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

eliminate several const_casts.

Make CallSite implicitly convertible to ImmutableCallSite.

Rename the getModRefBehavior for intrinsic IDs to
getIntrinsicModRefBehavior to avoid overload ambiguity with CallSite,
which happens to be implicitly convertible to bool.

Start cleaning up MergeFunctions to look more like the rest of LLVM. The
primary change here is to move the methods responsible for comparison into the
new FunctionComparator object. Some comments added. There's more to do.

exactly what bugpoint expected it to do.

There was also only one user of
BlockExtractorPass(const std::vector<BasicBlock*> &B), so just remove it and
make BlockExtractorPass read BlockFile.

This fixes bugpoint's block extraction.

alloca instructions (constrained by their internal encoding),

generated huge alignment values (null is infinitely aligned).
This fixes undefined behavior noticed by John Regehr.

dereference is theoretically infinite. Put a cap on the computed
alignment to avoid overflow, noticed by John Regehr.

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.
