re PR rtl-optimization/32450 (-pg causes miscompilation)
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.

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