obstacks: use obstack_blank_fast where possible.
In preparation for gnulib API change to obstacks, where
obstack_blank cannot shrink memory use any more.
* m4/macro.c (trace_flush): `start - len` can be negative, so
call obstack_blank_fast, which accepts negative arguments.
* modules/m4.c (m4_make_temp): Likewise... -1 is always negative!
