Log:
    PR target/47564
    * toplev.c (target_reinit): Save and restore *crtl and regno_reg_rtx
    around backend_init_target and lang_dependent_init_target calls.
    * cgraphunit.c (cgraph_debug_gimple_stmt): New function.
    (verify_cgraph_node): Don't call set_cfun here.  Use
    cgraph_debug_gimple_stmt instead of debug_gimple_stmt.
    Set error_found for incorrectly represented calls to thunks.

    * gcc.target/i386/pr47564.c: New test.
