676dd7c80b When the register allocator runs out of registers, spill a physical register around the def's and use's of the interval being allocated to make it possible for the interval to target a register and spill it right away and restore a register for uses. This likely generates terrible code but is before than aborting.

447ff68c08 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.

034f60ed24 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.

82e4289fc7 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.)
