1f22d9154a Change legalizeop of FP_ROUND and FP_EXTEND to not fall through
into the ANY_EXTEND/ZERO_EXTEND/SIGN_EXTEND code to simplify it.

Unmerge the code for FP_ROUND and FP_EXTEND from each other to 
make each one simpler.

fbb75278b2 introduce a isTypeInSSEReg predicate, which allows us to simplify
some code.  No functionality change.

41e1fd13b2 My previous commit had an incomplete message, it should have been:
make the 'fp return in ST(0)' optimization smart enough to
look through token factor nodes.  THis allows us to compile 
testcases like CodeGen/X86/fp-stack-retcopy.ll into:

_carg:
	subl	$12, %esp
	call	L_foo$stub
	fstpl	(%esp)
	fldl	(%esp)
	addl	$12, %esp
	ret

instead of:

_carg:
	subl	$28, %esp
	call	L_foo$stub
	fstpl	16(%esp)
	movsd	16(%esp), %xmm0
	movsd	%xmm0, 8(%esp)
	fldl	8(%esp)
	addl	$28, %esp
	ret

Still not optimal, but much better and this is a trivial patch.  Fixing 
the rest requires invasive surgery that is is not llvm 2.2 material.

81e35b4d47 I noticed that the trampoline straightening transformation could
drop attributes on varargs call arguments.  Also, it could generate
invalid IR if the transformed call already had the 'nest' attribute
somewhere (this can never happen for code coming from llvm-gcc,
but it's a theoretical possibility).  Fix both problems.

554971a6d6 Improve the FP stackifier to decide all on its own whether
an instruction kills a register or not.  This is cheap and 
easy to do now that instructions record this on their flags,
and this eliminates the second pass of LiveVariables from the
x86 backend.  This speeds up a release llc by ~2.5%.
