Austin Clements 48f990b4a5 cmd/compile: fix GOEXPERIMENT=preemptibleloops type-checking
This experiment has gone stale. It causes a type-checking failure
because the condition of the OIF produced by range loop lowering has
type "untyped bool". Fix this by typechecking the whole OIF statement,
not just its condition.

This doesn't quite fix the whole experiment, but it gets further.
Something about preemption point insertion is causing failures like
"internal compiler error: likeliness prediction 1 for block b10 with 1
successors" in cmd/compile/internal/gc.
