middle-end/114681 - condition coverage and inlining

When inlining a gcond it can map to multiple stmts, esp. with
non-call EH.  The following makes sure to pick up the remapped
condition when dealing with condition coverage.

	PR middle-end/114681
	* tree-inline.cc (copy_bb): Key on the remapped stmt
	to identify gconds to have condition coverage data remapped.

	* gcc.misc-tests/gcov-pr114681.c: New testcase.
