PR jit/63854: Add support for running "make check-jit" under valgrind

gcc/testsuite/ChangeLog:
    PR jit/63854
    * jit.dg/jit.exp (report_leak): New.
    (parse_valgrind_logfile): New.
    (fixed_host_execute): Detect if RUN_UNDER_VALGRIND is present
    in the environment, and if so, run the executable under
    valgrind, capturing valgrind's output to a logfile.  Parse the
    log file, generating PASSes and XFAILs for the summary of leaks.
    Use "wait" before "close": valgrind might not have finished
    writing the log out before we parse it, so we need to wait for
    the spawnee to finish.
