[x86] add sqrt tests for partially-inline-libcalls (PR31455) llvm-svn: 318630

; We have to assume that errno can be set, so we have to make a libcall in that case.

; Note: This is really a test of the -partially-inline-libcalls IR pass (and we have an IR test
; for that), but we're checking the final asm to make sure that comes out as expected too.
