Right now, the pass does not optimize tail recursions 
involving multiple return values.

add(Pass *) as a pure virtual member function. This will allow all
the various addPassesTo* functions in LLVM to avoid hard-coding what
type of PassManager is used.

If there are multiple register classes that a register belongs to, return the super-class (e.g. on x86, returns GR32, not GR32_).

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.

instead of:

_test:
	subl	$12, %esp
	#IMPLICIT_DEF %xmm0
	movsd	%xmm0, (%esp)
	fldl	(%esp)
	addl	$12, %esp

RET instruction instead of using FpSET_ST0_32.  This also generalizes
the code to handling returning of multiple FP results.

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.

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.)
