has no stores between the load and the end of block.  This works 
great and sinks hundreds of stores, but we can't turn it on because
machineinstrs don't have volatility information and we don't want to
sink volatile stores :(

both work right according to the new flags.

This removes the TII::isReallySideEffectFree predicate, and adds
TII::isInvariantLoad. 

It removes NeverHasSideEffects+MayHaveSideEffects and adds
UnmodeledSideEffects as machine instr flags.  Now the clients
can decide everything they need.

I think isRematerializable can be implemented in terms of the
flags we have now, though I will let others tackle that.

Likewise fix up a bunch of other libcalls.  While
there I remove NEG_F32 and NEG_F64 since they are
not used anywhere.  This fixes 9 Ada ACATS failures.

Clean up StrongPHIElimination a bit, and add some more comments to the internal structures.  There's
still more work to do on this front.

_test:

instead of code like this:

These are now private values which are only to be used to statically

some clients over to using the predicates instead of Flags directly.

Evan, please review the comments I added to getNumDefs to make sure
that they are accurate, thx.
