[PATCH 3/6] d3d11/tests: Add test for SM4 sample_l instruction.

[Henri Verbeet]

There seems to be a good amount of overlap between this test and
test_texture(). Would it make sense to merge them? Also, I assume
you'll add a d3d10core version of the test as well?

A struct vec4 would perhaps be more appropriate. IIRC MSVC gets a bit
unhappy about initializing floating-point variables with anything
other than floating-point constants, so it would perhaps be better to
use 0.0f here. However, ...

... I don't think you should need to pass in initial data in the first place.
