92c4b06513 Use ZEND_UNREACHABLE() instead of ZEND_ASSERT(0) 
Instead of marking unreachable code with `ZEND_ASSERT(0)`, we introduce
`ZEND_UNREACHABLE()`, so that MSVC which does not consider `assert(0)`
to mark unreachable code does no longer trigger C4715[1] warnings in
debug builds.  This may be useful for other compilers as well.

4edce91fae Avoid unnecessary linking of Windows DLLs 
For snapshot builds (`--enable-snapshot-build`), after the build has
been completely finished, running `nmake` causes a lot of DLLs to be
rebuilt.  The problem is that the build folders OptimizerObj and
opcache_jit are dependencies of the main PHP DLL, but these folders do
not exists in the source tree, so nmake assumes it has to re-link the
main PHP DLL, and that makes several other DLLs stale.

We solve that by mirroring the folder structure of the respective
source folders.

83a77015ad Add helper APIs for maybe-interned string creation 
Add ZVAL_CHAR/RETVAL_CHAR/RETURN_CHAR as a shortcut for using
ZVAL_INTERNED_STRING and ZSTR_CHAR.

Add zend_string_init_fast() as a helper for the empty string /
one char interned string / zend_string_init() pattern.

Also add corresponding ZVAL_STRINGL_FAST etc macros.

Closes GH-5684.

543684e796 Optimize out no-op yield from statements 
If the array is empty, then I'd expect that the generator is never left,
and that can be converted to a no-op and the return value would always be `null`.

Make `yield from [];` as efficient as `if (false) { yield null; }`
when opcache's sccp pass is enabled.

`zend_llist_add_element()` and `zend_llist_prepend_element()` now
explicitly expect a *const* pointer.

We use the macro `ZEND_VOIDP()` instead of a `(void*)` cast to suppress
C4090; this should prevent accidential removal of the cast by
clarifying the intention, and makes it easier to remove the casts if
the issue[1] will be resolved sometime.

975acfe71e Pass zend_string message to zend_error_cb 
This makes the zend_error_cb API simpler, and avoid formatting
the same message in multiple places.

It should be noted that the passed zend_string is always
non-persistent, so if you want to store it persistently somewhere,
you may still need to duplicate it.

The last_error_message is cleared a bit more aggressive, to make
sure it doesn't hang around across allocator life-cycles.

Closes GH-5639.
