(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.

remove Evan's "ugly hack" that sorta attempted to get
x86-64 return conventions correct, but was never enabled.
We can now do the "right thing" with multiple return values.

Enable support for returning two long-double values in 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.

Teach masked value is zero about add and sub, and use MVIZ to
simplify things like (X & 4) >> 1 == 2  --> (X & 4) == 4.
