Fix GH-18107: Opcache CFG jmp optimization with try-finally breaks the exception table 
If there's a try-finally where the try_op starts on a basic block with a
single JMP, and the JMP optimization causes that basic block to become
unreachable, then we update try_op.
In this case, there is no catch_op, so try_op is erroneously set to 0,
we should instead set it to `b->start`.

Closes GH-18110.

Fix ZEND_MATCH_ERROR misoptimization 
op1 of ZEND_MATCH_ERROR, which refers to the match expression, is not freed by
MATCH_ERROR itself. Instead, it is freed by ZEND_HANDLE_EXCEPTION. For normal
control flow, a FREE is placed at the end of the match expression.

Since FREE may appear after MATCH_ERROR in the opcode sequence, we need to
correctly handle op1 of MATCH_ERROR as alive.

Fix create_object checks 
Since PHP 8.3, object handlers may be changed by setting

Fix range inference since "proper-range-semantics" RFC 
* Arrays returned from range are never empty
* When step is a double value representable by a long, it is coerced implicitly.
  As such, passing a double step no longer guarantees that the result is a
  non-int array.

7585cf6952 Fix GH-12953: SSA integrity verification failed when loading composer classmaps with more than 11k elements 
This is a false positive. The cycle detection code stops at 10.000
iterations. Instead of stopping at a fixed amount, make it more robust
by implementing Floyd's cycle detection algorithm.

d8ef868b92 Return value of mb_get_info can be NULL 
This has been the case at least since PHP 5.4. Thanks to Girgias for
pointing it out.

It appears that there are several global variables internal to mbstring
which can be queried via mb_get_info() and which could be NULL, but
at the very least, we know that "mbstring.http_input" is one of them.
