Log:
        PR rtl_optimization/32450
        * function.c (thread_prologue_and_epilogue_insns): Emit blockage insn
        to ensure that instructions are not moved into the prologue when
        profiling is on.  Remove unused prologue_end variable.
        (expand_function_end): Emit blockage insn instead of ASM_INPUT rtx
        as a scheduling barrier.

testsuite/ChangeLog:

        PR rtl_optimization/32450
        * gcc.dg/pr32450.c: New runtime test.
