two address instructions.  We need to keep track of things we've processed AS USES
independetly of whether we've processed them as defs.

This fixes all known miscompilations when reconstruction is turned on.

- Fix bugs 3194, 3195: i128 load/stores produce correct code (although, we
  need to ensure that i128 is 16-byte aligned in real life), and 128 zero-
  extends are supported.
- New td file: SPU128InstrInfo.td: this is where all new i128 support should
  be put in the future.
- Continue to hammer on i64 operations and test cases; ensure that the only
  remaining problem will be i64 mul.

AddPseudoTwoAddrDeps. This lets the scheduling infrastructure
avoid recalculating node heights. In very large testcases this
was a major bottleneck. Thanks to Roman Levenstein for finding
this!

As a side effect, fold-pcmpeqd-0.ll is now scheduled better
and it no longer requires spilling on x86-32.

however this is currently dead because for the moment
aliases aren't allowed to have this linkage type.
