[Mesa-dev] [MOSTLY RESEND PATCH 0/8] Emit SPIR-V pre-pre-work

[Ian Romanick]

Most of these patches have been on the list at least once.  Major
changes are:

- Patches 1, 6, and 7 had a bunch of changes due to rebasing.

- Patches 2 had some minor changes due to rebasing.

- Patches 3 and 8 are new.

Only patches 4 and 5 should be unchanged.  The whole series passes the
Intel CI, but I haven't tested the changes to other drivers.
