History

Chris Lattner 17f0cd3cc1 teach libanalysis to simplify vector loads with bitcast sources. This

implements something out of Target/README.txt producing:

_foo:                                                       ## @foo
	movl	4(%esp), %eax
	movapd	LCPI1_0, %xmm0
	movapd	%xmm0, (%eax)
	ret	$4

instead of:

_foo:                                                       ## @foo
	movl	4(%esp), %eax
	movapd	_b, %xmm0
	mulpd	LCPI1_0, %xmm0
	addpd	_a, %xmm0
	movapd	%xmm0, (%eax)
	ret	$4
