Use the same stack limit check already used elsewhere in compilation.

I think this needs a different solution, I think we should return a success/failure status from zend_build_cfg depending on the used stack space and then bail out of zend_jit_build_cfg like we already do if there are too many blocks:

php-src/ext/opcache/jit/zend_jit.c

Lines 926 to 931 in c8a8d8a

	/* Don't JIT huge functions. Apart from likely being detrimental due to the amount of
	* generated code, some of our analysis is recursive and will stack overflow with many
	* blocks. */
	if (cfg->blocks_count > 100000) {
	return FAILURE;
	}

EDIT: I tried that here: #14432
