the new StructType::get method.  The second NULL
is to pacify the gcc warning mechanism.  This
patch compiles but is otherwise untested.

flags.  This is needed by the new legalize types
infrastructure which wants to expand the 64 bit
constants previously used to hold the flags on
32 bit machines.  There are two functional changes:
(1) in LowerArguments, if a parameter has the zext
attribute set then that is marked in the flags;
before it was being ignored; (2) PPC had some bogus
code for handling two word arguments when using the
ELF 32 ABI, which was hard to convert because of
the bogusness.  As suggested by the original author
(Nicolas Geoffray), I've disabled it for the moment.
Tested with "make check" and the Ada ACATS testsuite.

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

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.
