0bd260218b Fix stack limit on ASAN/MSAN (#14771)
Increase the reserved stack size in ASAN builds, as instrumentation use more stack.
Increase the max allowed stack size in some tests, and enable these tests under ASAN.
Use __builtin_frame_address(0), instead of some stack variable, when we need a stack address, as ASAN may store local variables outside of the real stack.

(e.g. 32-bit CLANG build with address sanitizer)

cf77762970 Skip tests under MSAN
Stack overflows can be detected as long as C stack frames between two
execute_ex() calls use less than zend.reserved_stack_size bytes of stack.

The default value of zend.reserved_stack_size accounts for the largest stack
users, but MSAN instrumentation increases usage considerably: php_pcre2_match
uses more than 200KiB of stack in some MSAN build, compared to 20KiB without MSAN
according to -fstack-usage.
