[PATCH][PR tree-optimization/pr67755] Fix profile insanity adjustments
PR tree-optimization/pr67755
* tree-ssa-threadupdate.c (struct ssa_local_info_t): Add new field
"need_profile_correction".
(thread_block_1): Initialize new field to false by default. If we
have multiple thread paths through a common joiner to different
final targets, then set new field to true.
(compute_path_counts): Only do count adjustment when it's really
needed.
PR tree-optimization/67755
* gcc.dg/tree-ssa/pr67755.c: New test.
