Does that also provent *writing* a PCH with -gstabs?

The point of making asm_out_file write-only and stop front ends from
writing to it, is to postpone opening asm_out_file to some point as
late as possible. For this to work, attempting to write a PCH must
also be disabled (because of the early stabs output to asm_out_file).

Ciao!
