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
