Cherry Zhang 498eaee461 cmd/internal/obj/x86: mark 2-instruction TLS access nonpreemptible 
The 2-instruction TLS access sequence
	MOVQ TLS, BX
	MOVQ 0(BX)(TLS*1), BX
is not async preemptible, as if it is preempted and resumed on a
different thread, the TLS address may become invalid.

May fix #35349. (This is a rare failure and I haven't been able
to reproduce it.)
