Make it possible for the jit to deopt to tier1 upon interrupts #132532

@iritkatriel

Description

@iritkatriel

Make CHECK_PERIODIC a separate instruction, use it instead of the _CHECK_PERIODIC uops for calls.
Then the JIT can safely abort the check instruction. For jumps we don't need to do this because the top appears before the jump instruction has any side effect on program state.
