1de43ede89 Fix the remaining TCL-style quotes found in the testsuite. This is 
another mechanical change accomplished though the power of terrible Perl
scripts.

I have manually switched some "s to 's to make escaping simpler.

While I started this to fix tests that aren't run in all configurations,
the massive number of tests is due to a really frustrating fragility of
our testing infrastructure: things like 'grep -v', 'not grep', and
'expected failures' can mask broken tests all too easily.

Essentially, I'm deeply disturbed that I can change the testsuite so
radically without causing any change in results for most platforms. =/

a06ec9efe1 Now not UINT_TO_FP is legal (it's marked custom), dag combiner won't 
optimize it to a SINT_TO_FP when the sign bit is known zero. X86 isel should perform the optimization itself.

cda8875433 when we know the signbit of an input to uint_to_fp is zero, 
change it to sint_to_fp on targets where that is cheaper (and
visaversa of course).  This allows us to compile uint_to_fp to:

_test:
	movl	4(%esp), %eax
	shrl	$23, %eax
	cvtsi2ss	%eax, %xmm0
	movl	8(%esp), %eax
	movss	%xmm0, (%eax)
	ret

instead of:

	.align	3
LCPI1_0:					##  double
	.long	0	## double least significant word 4.5036e+15
	.long	1127219200	## double most significant word 4.5036e+15
	.text
	.align	4,0x90
	.globl	_test
_test:
	subl	$12, %esp
	movl	16(%esp), %eax
	shrl	$23, %eax
	movl	%eax, (%esp)
	movl	$1127219200, 4(%esp)
	movsd	(%esp), %xmm0
	subsd	LCPI1_0, %xmm0
	cvtsd2ss	%xmm0, %xmm0
	movl	20(%esp), %eax
	movss	%xmm0, (%eax)
	addl	$12, %esp
	ret
