[ftracer] Add caching of can_duplicate_bb_p
The fix "[omp, ftracer] Don't duplicate blocks in SIMT region" adds iteration
over insns in ignore_bb_p, which makes it more expensive.
Counteract this by piggybacking the computation of can_duplicate_bb_p onto
count_insns, which is called at the start of ftracer.
Bootstrapped and reg-tested on x86_64-linux.
gcc/ChangeLog:
2020-10-05 Tom de Vries <tdevries@suse.de>
* tracer.c (count_insns): Rename to ...
(analyze_bb): ... this.
(cache_can_duplicate_bb_p, cached_can_duplicate_bb_p): New function.
(ignore_bb_p): Use cached_can_duplicate_bb_p.
