Pecl 8.4 tracing JIT crash

[danog]

Description

Running pecl install xdebug-beta in the image built through https://github.com/danog/jit_bugs/ fails with the following assertion (at least on arm64):

php: ext/opcache/jit/zend_jit_trace.c:8748: int zend_jit_trace_exit(uint32_t, zend_jit_registers_buf *): Assertion `((execute_data)->opline) >= ((execute_data)->func)->op_array.opcodes && ((execute_data)->opline) < ((execute_data)->func)->op_array.opcodes + ((execute_data)->func)->op_array.last' failed.

I searched and found we have an old bug report that also hit the exact same assertion, but with a standalone reproducer: #9011
Tentatively making this verified, if the old bug report is fixed we can reverify if this was a duplicate or not.

Actually, while debugging the other issue I start to believe that they might be not related because the other is Windows-specific I think.

Thanks for the fixes @dstogov! Do you think you could merge them into the 8.4.2 branch?
