[gimple] Move can_duplicate_bb_p to gimple_can_duplicate_bb_p
The function gimple_can_duplicate_bb_p currently always returns true.
The presence of can_duplicate_bb_p in tracer.c however suggests that
there are cases when bb's indeed cannot be duplicated.
Move the implementation of can_duplicate_bb_p to gimple_can_duplicate_bb_p.
Bootstrapped and reg-tested on x86_64-linux.
Build x86_64-linux with nvptx accelerator and tested libgomp.
No issues found.
As corner-case check, bootstrapped and reg-tested a patch that makes
gimple_can_duplicate_bb_p always return false, resulting in
PR97333 - "[gimple_can_duplicate_bb_p == false, tree-ssa-threadupdate]
ICE in duplicate_block, at cfghooks.c:1093".
gcc/ChangeLog:
2020-10-09 Tom de Vries <tdevries@suse.de>
* tracer.c (cached_can_duplicate_bb_p, analyze_bb): Use
can_duplicate_block_p.
(can_duplicate_insn_p, can_duplicate_bb_no_insn_iter_p)
(can_duplicate_bb_p): Move and merge ...
* tree-cfg.c (gimple_can_duplicate_bb_p): ... here.
