1bd44363f2 Change the model for FP Stack return to use fp operands on the 
RET instruction instead of using FpSET_ST0_32.  This also generalizes
the code to handling returning of multiple FP results.

d6819da453 Generalize ExpandIntToFP to handle the case where the operand is legal 
and it's the result that requires expansion. This code is a little confusing
because the TargetLoweringInfo tables for [US]INT_TO_FP use the operand type
(the integer type) rather than the result type.

d3090bcfc8 If a register operand comes from the variadic part of a node, don't

0fb187f81b Disable prolog code that aligns the stack when a 
local object of >16 byte alignment exists.  It does not
work and getting it to work is not trivial, as explained
in the comment.  This fixes all the remaining ppc32
failures in the struct-layout-1 part of the gcc testsuite.

(gcc does not support this either, and the only way to
get such an object is with __attribute__((aligned)) or
generic vectors; it can't be done in a standard-conforming
program, or with Altivec.  So I think disabling it is OK.)
