Handle MESA_FORMAT_RGBA_16 in _mesa_format_matches_format_and_type().

The profile in the winehq bug does look somewhat similar to the one for bug 55396. Does this patch make it any better?

I have the same like without patches. Anything better.

Also I added sysprof from wine bugzilla to make it more clear.

That was just the patch you attached, not the sysprof.

My mistake, sorry.

That's short messages, so I'm not adding attachments.

Where I noticed lines:

I don't see this lines using old mesa 7.11 (where everything is OK). Maybe there is a problem?

Same note about INTEL_DEBUG=perf environment variable here.
