07cabb9432 Redo the 3 existing low-precision expansions to 
use float constants.  An oversight by the numerics
people who supplied this.

9a0d1ba051 Revert my previous change -- the subtraction of two constants was a no-op 
before. This is taken care of in the selection DAG pass. In my opinion, this
should be in one place or the other. I.e., it should probably be removed from
the DAG combiner (along with the other arithmetic transformations on constants
that are essentially no-ops).

Not yet turned on, it needs to support sext / zext of arguments and result.

fec2c2bf5e When PruneEH turned an invoke into an ordinary 
call (thus changing the call site) it didn't
inform the callgraph about this.  But the
call site does matter - as shown by the testcase,
the callgraph become invalid after the inliner
ran (with an edge between two functions simply
missing), resulting in wrong deductions by
GlobalsModRef.
