We need to properly handle `MapViewOfFileEx()` failures; otherwise strange error messages might be reported in the following. E.g. bug72858.phpt is likely to fail on 32bit Windows with "Warning: shm_attach(): Failed for key 0x64: File exists".

This looks like a really nice fix. Can I ask if there is any desire to get this merged? Looking into newer PHP build failures on Windows, it does seem that they could be influenced by seemingly small bugs like this fixes. |

MapViewOfFileEx()failures; otherwise strange error messages might be reported in the following. E.g. bug72858.phpt is likely to fail on 32bit Windows with "Warning: shm_attach(): Failed for key 0x64: File exists".Note that this issue also affects older PHP versions, but the chance of
MapViewOfFileEx()failing is very small there, because we only tried to map an info segment there, instead of trying to map the whole segment now, due to #8648.
