zend_compiler, ...: use uint8_t instead of zend_uchar (#10621) 
`zend_uchar` suggests that the value is an ASCII character, but here,
it's about very small integers.  This is misleading, so let's use a
C99 integer instead.

On all architectures currently supported by PHP, `zend_uchar` and
`uint8_t` are identical.  This change is only about code readability.

Fix GH-10168: heap-buffer-overflow at zval_undefined_cv 
The problem is that we're using the variable_ptr in the opcode handler
*after* it has already been destroyed. The solution is to create a
specialised version of zend_assign_to_variable which takes in two
destination zval pointers.

dc5475c191 Save previous observer on the VM stack 
This avoids a possible significant performance penalty, when some leaf function was observed, deep in the stack.
As a side effect, we are not iterating over prev_execute_data anymore and thus, non-observed fake frames, possibly on stack, cannot have any impact on the observer anymore (especially within zend_observer_fcall_end_all).

Saving the previous observer happens now directly on the VM stack. If there is any observer, function frames are allocated an extra zval (the last temporary), which will, on observed frames, contain the previous observed frame address.

a4fa00ead3 Reuse wrong string offset logic in jit 
JIT contains a copy of this function that effectively only differs
by fetching current_execute_data from EG. We can do that in the VM
version as well, as this is just used to throw an error.

Export the VM function and reuse it in JIT.
