495304e351 Make it possible to get an empty struct using
the new StructType::get method.  The second NULL
is to pacify the gcc warning mechanism.  This
patch compiles but is otherwise untested.

276dcbdc8d Introduce a new node for holding call argument
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.

920c37afc5 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.

0353526ed1 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.

41dc0fcb68 Teach masked value is zero about add and sub, and use MVIZ to
simplify things like (X & 4) >> 1 == 2  --> (X & 4) == 4.

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

94202018c5 Fix live variables issues:
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue.
2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register:
   = EAX, AX<imp-use,kill>
...
AX =
In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things.
