nir/algebraic: Optimize common array indexing sequence

Some shaders include code that looks like:

   uniform int i;
   uniform vec4 bones[...];

   foo(bones[i * 3], bones[i * 3 + 1], bones[i * 3 + 2]);

CSE would do some work on this:

   x = i * 3
   foo(bones[x], bones[x + 1], bones[x + 2]);

The compiler may then add '<< 4 + base' to the index calculations.
This results in expressions like

   x = i * 3
   foo(bones[x << 4], bones[(x + 1) << 4], bones[(x + 2) << 4]);

Just rearranging the math to produce (i * 48) + 16 saves an
instruction, and it allows CSE to do more work.

   x = i * 48;
   foo(bones[x], bones[x + 16], bones[x + 32]);

So, ~6 instructions becomes ~3.

i965/fs: Estimate maximum sampler message execution size more accurately.

The current logic used to determine the execution size of sampler
messages was based on special-casing several argument and opcode
combinations, which unsurprisingly missed the possibility that some
messages could exceed the payload size limit or not depending on the
number of coordinate components present.  In particular:

 - The TXL, TXB and TEX messages (the latter on non-FS stages only)
   would attempt to use SIMD16 on Gen7+ hardware even if a shadow
   reference was present and the texture was a cubemap array, causing
   it to overflow the maximum supported sampler payload size and
   crash.

 - The TG4_OFFSET message with shadow comparison was falling back to
   SIMD8 regardless of the number of coordinate components, which is
   unnecessary when two coordinates or less are present.

Both cases have been handled incorrectly ever since cubemap arrays and
texture gather were respectively enabled (the current logic used by
the SIMD lowering pass is almost unchanged from the previous no16
fall-back logic used pre-SIMD lowering times).

Fixes the following GL4.5 conformance test on Gen7-8 (the bug also

i965/fs: Return zero from fs_inst::components_read for non-present sources.

This makes it easier for the caller to find out how many scalar

longer need to special-case BAD_FILE in the implementation of

egl/dri2: dri2_make_current: Release previous context's display

eglMakeCurrent can also be used to change the active display. In that
case, we need to decrement ref_count of the previous display (possibly
destroying it), and increment it on the next display.

Also, old_dsurf/old_rsurf cannot be non-NULL if old_ctx is NULL, so
we only need to test if old_ctx is non-NULL.

v2: Save the old display before destroying the context.
