With this pass, StrongPHIElim can compile very simple testcases correctly.  There's still a ways
to go before it's ready for prime time, though.

Transform (zext (or (icmp), (icmp))) to (or (zext (cimp), (zext icmp))) if at least one of the (zext icmp) can be transformed to eliminate an icmp.

This fires dozens of times across spec and multisource, but I don't know
if it actually speeds stuff up.  Hopefully the testers will show something
nice :)

adding <map> to many files that actually do need it.

dynamic initialization.

the number of objects requiring static constructors in a typical
LLVM build by around 20%.

from their aggregate operands by moving the getresult
instructions.

This verifies kill info for "ret" fp operands is right.
