    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.
