here:

1) We need to avoid processing sigma nodes as phi nodes for constraint generation.
2) We need to generate constraints for comparisons against constants properly.

This includes our first working ABCD test!

graphs being produced.  The cause was that we were incorrectly marking sigma instructions as
processed after handling the sigma-specific constraints for them, potentially neglecting to
process them as normal instructions as well.

Unfortunately, the testcase that inspired this still doesn't work because of a bug in the solver,
which is next on the list to debug.

when both the source and dest are illegal types, since it would cause
the phi to grow (for example, we shouldn't transform test14b's phi to
a phi on i320).  This fixes an infinite loop on i686 bootstrap with
phi slicing turned on, so turn it back on.

1. rename the movhp patfrag to movlhps, since thats what it actually matches
2. eliminate the bogus movhps load and store patterns, they were incorrect.  The load transforms are already handled (correctly) by shufps/unpack.
3. revert a recent test change to its correct form.

computation is legal or if both the source and dest
are illegal.  This prevents instcombine from changing big
chains of computation into i64 on 32-bit targets for 
example.
