2a545ba946 Fix #80175: PHP8 RC1 - JIT Buffer not working 
On Windows, `SUCCESSFULLY_REATTACHED` does not imply that the process
has already been properly initialized; thus we must not skip some setup
steps in `zend_jit_startup()`.

Closes GH-6268.

fdd9018bdf Support uuencoding empty string 
Cross checking implementations from other languages, empty strings
are always allowed. PHP's output is peculiar due to it's insistence
to encode a trailing \0, but otherwise sensible and does round-trip
as expected.
