If a function always returns a constant, replace all calls sites with that
...
constant value. This makes the return value dead and allows for
simplification in the caller.
This implements IPConstantProp/return-constant.ll
This triggers several dozen times throughout SPEC.

Actually, leave the check in. This prevents us from counting dead arguments
...
as IPCP opportunities.

Do not let dead constant expressions hanging off of functions prevent IPCP.
...
This allows to elimination of a bunch of global pool descriptor args from
programs being pool allocated (and is also generally useful!)

'Pass' should now not be derived from by clients. Instead, they should derive
...
from ModulePass. Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

do something dumb, and inefficient, but more complete.
