Same trick as in fb: just do a normal GetImage and deal with the
planemask on the CPU if you have to. Since the software fallback hit for
glamor is pretty brutal, this is a much more impressive win for glamor
than it was for fb:

Measured with Xephyr -glamor on Skylake GT3e.

Instead of passing the destination drawable, just pass the depth, as
the underlying functions need only that to check whether the planemask
is going to work.
This API change will allow higher level functions to not need the
destination pixmap.

It turns out putimage doesn't use the GC tile or stipple anyway, so
there's no need to do this.
