re PR ipa/63909 (ICE: SIGSEGV in ipa_icf_gimple::func_checker::compare_bb())
PR ipa/63909
* gimple-iterator.h (gsi_start_bb_nondebug): New function.
* ipa-icf-gimple.c (func_checker::compare_bb): Correct iteration
replaces loop based on precomputed number of non-debug statements.
* gcc.dg/ipa/pr63909.c: New test.
