85e7ac0353 Fix an altivec constant miscompilation that Duncan found through
his work on legalizetypes.

5ac319ac71 Add support for 128 bit multiplicative operations.
Lack of these caused a bootstrap failure with Fortran
on x86-64 with LegalizeTypes turned on.  While there,
be nice to 16 bit machines and support expansion of
i32 too.

be1ad4de29 Add a mysteriously missing libcall, FPTOSINT_F80_I32.

expansion for these.

d16918f843 Restructure dead argument elimination, try #3 :-)
Rewrite the DeadArgumentElimination pass, to use a more explicit tracking of
dependencies between return values and/or arguments. Also make the handling of
arguments and return values the same.

The pass now looks properly inside returned structs, but only at the first
level (ie, not inside nested structs).

This version fixed a few more bugs and was cleaned up a bit. It now passes all
of LLVM's testing, and should still pass SPEC2006. There is still a minor bug
with regard to returning nested structs. Since there is currently nothing that
emits such IR, I will fix that in a seperate commit (partly because it requires
a non-trivial fix).

ef0732d25a - Change the horrible N^2 isRegReDefinedByTwoAddr. Now callers must supply the operand index of def machineoperand and at most one full scan of non-implicit operands is needed.
- Change local register allocator to use the new isRegReDefinedByTwoAddr instead of reinventing the wheel.

b9c33c3229 Simplify hasNUsesOfValue and hasAnyUsesOfValue even more. This
makes their special-case checks of use_size() less beneficial,
so remove them. This eliminates all but one use of use_size(),
which is in AssignTopologicalOrder, which uses it only once for
each node, and so can reasonably afford to recompute it, as
this allows the UsesSize field of SDNode to be removed
altogether.

492f276cbc Move the IsVolatile and SVOffset fields into the MemSDNode base
class, and store IsVolatile and Alignment in a more compact form.
This makes AtomicSDNode slightly larger, but it shrinks LoadSDNode
and StoreSDNode, which are much more common and are the largest of
the SDNode subclasses. Also, this lets the isVolatile() and
getAlignment() accessors be non-virtual.
