Separate zend_jit_var_supports_reg() and cleanup

Add tracing JIT guards for INTI_FCALL_BY_NAME and INIT_NS_FCALL_BY_NAME

JIT for INIT_NS_FCALL_BY_NAME

JIT for FETCH_THIS

Change jit_trace_stack_frame layout

JIT for STRLEN

JIT for ECHO and variable string operands

JIT for SEND_FUNC_ARG

JIT for ZEND_CHECK_FUNC_ARG

Eliminate run-time check

Improved JIT for BIND_GLOBAL

Use different scratch register in read_obj

We already use r0 to hold the zval.

Explicitly pass scratch register to SAVE_VALID_OPLINE

Improved JIT for ZEND_ASSIGN

Slightly deduplicate code

This code is the same in both branches, extract it.

Remove "safe" argument from ZVAL_PTR_DTOR

This is no longer used

Merge EX variants of INFO macros

Merge zend_may_throw(_ex)

Explicitly pass ssa_op in the places that don't do so yet.

Tracing JIT (it doesn't support register allocation yet)

Use opcache.jit=1255 to swith it on (the third digit 5 really matters)
Use opcache.jit_debug=0xff001 to see how it works and what

Avoid more null arithmetic

Remove more null arithmetic UB

Introduce an EX_NUM_TO_VAR macro to mirror EX_VAR_TO_NUM and
replace usages of the ZEND_CALL_VAR_NUM(NULL) pattern.

Fix JIT trait type errors

We need to load EX->func here rather than use a hardcoded op_array,
as it may be copied with adjusted scope for traits.

Removed unused macro

Save delayed call frame
