Bug description:General performance regression with PHP 7.4 on Windows
Description:
------------
The reworking of the Windows stat implementation for PHP 7.4[1]
caused an fstat() related performance regression compared to PHP
7.3, which is most serious with OPcache disabled, where it makes
scripts and applications about 10% slower.
This is because fstat() now tries to retrieve the filename of the
stream to properly set the executable bits (S_IEXEC) of the
st_mode member, while formerly it did not (instead native Windows
fstat() and friends have been called).
