x86-64 return conventions correct, but was never enabled.
We can now do the "right thing" with multiple return values.

ST(0)/ST(1).

This allows us to compile fp-stack-2results.ll into:

_test:
	fldz
	fld1
	ret

which returns 1 in ST(0) and 0 in ST(1).  This is needed for x86-64
_Complex long double.

simplify things like (X & 4) >> 1 == 2  --> (X & 4) == 4.

since it is obvious that the shift doesn't remove any bits.

LiveVariables analysis now uses intersect for the merge of block-level expression liveness information.
The rationale is that a block-level expression cannot be live in a parent block unless it is live in all of the successor blocks.

- Fix loop nest.
- Use RetVals.size()
- Check for null return value.

Fix bugs encountered, mostly due to range matching for immediates;
the CellSPU's 10-bit immediates are sign extended, covering a
larger range of unsigned values.
