Cleanup abstract test usage

Allow keeping result of FETCH_DIM_R in CPU register

We track only arguments of user functions on abstract stack

Separate and fix deoptimization code generator

Prevent incorrect trasing JIT TSSA usage for range() result type inference

Drop no-op dasm_growpc() call

This doesn't do anything, as maxpc=0 is passed. However, ubsan
complains about the memset of a null pointer, so avoid it.

Keep CPU regesters used by deoptimizer

Side exit on overflow

Eliminate useless exception checks

Eliminate some reference-counting

Check type guard on result of FETCH_OBJ_R/IS instructions

Fixed tracing JIT for ASSIGN to typed reference

Check type guard on result of FETCH_DIM_R/IS instructions

Implement match expression

RFC: https://wiki.php.net/rfc/match_expression_v2

Closes GH-5371.

Make tracing JIT to support operator overloading independently from opcache.optimization_level ini directive.

Fixed register allocation for tests/lang/operators/preinc_basiclong_64bit.phpt

Prevent trace recorder reenterancing

Fixed tracing JIT support for extract()

JIT support for opcache restart

Fixed tracing JIT support for $http_response_header
