st/xa: Use PIPE_FORMAT_R8_UNORM when available

XA has been using L8_UNORM for a8 and yuv component surfaces.
This commit instead makes XA prefer R8_UNORM since it's assumed to have a
higher availability.

Also neither of these formats are suitable as destination formats using
destination alpha blending, so reject those operations.

    "If pipeline is a name that has been generated (without subsequent
    deletion) by GenProgramPipelines, but refers to a program pipeline

i965/vec4: Fix saturation errors when coalescing registers

If the register types do not match and the instruction
that contains the final destination is saturated, register
coalescing generated non-equivalent code.

This did not happen when using IR because types usually
matched, but it is visible in nir-vec4.

For example,
   mov      vgrf7:D vgrf2:D
   mov.sat  m4:F vgrf7:F

is coalesced to:
   mov.sat  m4:D vgrf2:D

The patch prevents coalescing in such scenario, unless the
instruction we want to coalesce into is a MOV (without type
conversion implied). In that case, the patch sets the register
types to the type of the final destination.

Shader-db results in HSW (only vec4 instructions shown):

total instructions in shared programs: 1754415 -> 1754416 (0.00%)
instructions in affected programs:     74 -> 75 (1.35%)
helped:                                0
HURT:                                  1
GAINED:                                0
LOST:                                  0

Only one extra instruction in one of the shaders, that comes from
eliminating a saturation error by preventing register coalesce.
