Avoid loop throgh side_exit from the first trace instruction.

Fixed tracing JIT for CALL VM without global register variables

More accurate tracing JIT for RETURN with unknown return address

Prevent taking side traces for exceptional cases. Always exit to VM interpreter.

Avoid Program Counter guard in side trace started from Fake Init Fcall guard.

Make numeric operations on resources, arrays and objects type errors

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

Closes GH-5331.

Replace ZEND_ASSERT() by conditional compilation abort.
Prevent endless loop through ESCAPE code.

Improved tracing JIT for nested calls

white space fixes

JIT: Save opline before calling zend_timeout

tests/045.phpt started segfaulting, because the opline is not set
when zend_timeout is invoked.

Less conservative fix

I think it's reasonable to assume that the only possible types
are those that are declared, and null, because null is what
return_value is initialized to.

Fix JIT segfaults in FFI tests

Conservative fix that just disables this optimization.

Fixed incorrect side exit address

Use information about classes returned by internal functions

Fixed register allocation constraints

Fix OPcache build

`||` at the beginning of a line has special meaning for the DynAsm
preprocessor.

Register allocator and deoptimizer for tracing JIT.

[skip ci] Fix typos in jit code comments

And in Opcache's zend_cfg.h

Closes GH-5414

Improve registers reuse

Removed unused parameter

Fixed overflow handling

Register allocator refactoring

Save CPU regesters on side exit for deoptimization

Minor register allocator refactoring

Improve undefined variable error messages

Closes GH-5312
