- Revise previous patches of the same purpose by fixing
*) grep <PA> | not grep <PB> semantically is not the same as
CHECK: <PA>{{^<PB>.*$}} as the former will check all occurrences of <PA>
while the later only check the first match. As the result, CHECK needs
putting in all place where <PA> occurs.
*) grep <PA> | count <N> needs a final CHECK-NOT of the same pattern.
(As 'CHECK-<N>' is proposed for discussion, converting 'grep | count <N>'
where N > 1 is postponed.)

into a vector of zeros or undef, and when the top part is obviously
zero, we can just use movd + shuffle. This allows us to compile
vec_set-B.ll into:
_test3:
movl $1234567, %eax
andl 4(%esp), %eax
movd %eax, %xmm0
ret
instead of:
_test3:
subl $28, %esp
movl $1234567, %eax
andl 32(%esp), %eax
movl %eax, (%esp)
movl $0, 4(%esp)
movq (%esp), %xmm0
addl $28, %esp
ret
