5 years agost/dri: Perform MSAA downsampling for __DRI2_THROTTLE_COPYSUBBUFFER

st/dri: Perform MSAA downsampling for __DRI2_THROTTLE_COPYSUBBUFFER

glXCopySubBufferMESA copies data from the back buffer to the front,
so it needs to perform a MSAA downsampling operation just like
glXSwapBuffers would.

Currently, the CopySubBuffer implementations supply a throttle reason
of __DRI2_THROTTLE_SWAPBUFFERS, so they hit this path and work today.
But we'd like to avoid swapbuffer throttling in this case, so the next
patch will change that reason.

Additionally, it seems like if their operands are not aligned to 64

 "A word or doubleword operand that crosses a 4-byte boundary or a
 quadword operand that crosses an 8-byte boundary is considered
 unaligned and requires two separate memory bus cycles for access."

Forcing the u64 field to be aligned to 64 bits seems to make the unit

gitlab-ci: Use per-job ccache

Instead of a single cache shared between all jobs, but reduce the
maximum cache size to 1.5G (from 5G).

Rationale for smaller cache:

Pulling & pushing a 5G cache could take a long time. Consider
https://gitlab.freedesktop.org/mesa/mesa/-/jobs/684010 (click the "Show
complete raw" button to see timestamps): Pulling the cache took
1569927241-1569927194 = 47 seconds, pushing it 1569927671-1569927519
= 152, for a total of 199 seconds. The actual build took comparable
1569927518-1569927243 = 275 seconds, despite no cache hits from ccache.
In other words, the cache transfers almost doubled the job duration,
and they would have negated any build time benefits from ccache even
with a high cache hit rate.

Also, the smaller caches avoid blowing up storage requirements for them
too much.

Rationale for per-job caches:

Making a single cache significantly smaller might result in cached
build products from one job getting evicted by another job, reducing
the likelihood of cache hits from previous pipelines.
