Optimize code for FETCH_THIS + INIT_METHOD_CALL/ASSIGN_OBJ_OP/etc

JIT for INIT_METHOD_CALL

Simplify zend_jit_pre/post_inc/dec_typed_ref() helpers

JIT for PRE/POST_INC/DEC_OBJ

JIT for ASSIGN_OBJ_OP

JIT for ASSIGN_OBJ

JIT for FETCH_DIM_W/RW insructions

Fix call to type error functions from jit

Missed to adjust those calls.

Eliminate ZSTR_IS_INTERNED() check

Promote "undefined array key" notice to warning

This implements the last remaining part of the
https://wiki.php.net/rfc/engine_warnings RFC.

Closes GH-5927.

Merge common "cold" part

Implement 'Saner Numeric Strings' RFC:

This removes the -1 allow_error mode from is_numeric_string functions and replaces it by

Implement 'Saner Numeric Strings' RFC:

RFC: https://wiki.php.net/rfc/saner-numeric-strings

This removes the -1 allow_error mode from is_numeric_string functions and replaces it by
a trailing boolean out argument to preserve BC in a couple of places.

Most of the changes can be resumed to "numeric" strings which emitted a E_NOTICE now emit
a E_WARNING and "numeric" strings which emitted a E_WARNING now throw a TypeError.

This mostly affects:
- String offsets
- Arithmetic operations
- Bitwise operations

Closes GH-5762

Remove old code (BP_VAR_RW warning)

Fixed tracing JIT for ASSIGN to typed reference

JIT for array merging

Review the usage of apostrophes in error messages

Closes GH-5590

Handle dim_w undefined variable notice in JIT as well

Check for undef variable exception in SEND_VAR JIT

Add a return value to zend_jit_undefined_op_helper(), so we can
check for exception based on the return value, instead of fetching

JIT support for undefined index/offset handling

Fixed bug #79743 (Fatal error when assigning to array property with JIT enabled)

simple typo

Use cheaper zend_hash_find_ex() to handle IS_CONST index

Cheaper exception checks

Improved JIT for RECV and RECV_INIT instructions

Reduce amount of "cold" code generated for FETCH_OBJ_* instructions

Improve JIT for SEPARATE_ARRAY
