This test apparently requires an x86 target and is failing on numerous

bots ever since d0k fixed the CHECK lines so that it did something at
all.

It isn't actually testing SCEV directly but LSR, so move it into LSR and
the x86-specific tree of tests that already exists there. Target
dependence is common and unavoidable with the current design of LSR.
