tests: Test comparison and logic operators on SM1 vertex shaders.

Currently these are failing for SM1 because VKD3DSIH_SLT is not being
handled by spirv.c.

+% The main objective of this test is to see if operations for SM1 vertex shaders work, because they
+% have a different instruction set than pixel shaders.
+
+% Considerations so that the vertex shader output matches the pixel shader input properly on all
+% backends:
+% - sv_position must be the last field in the output signature.
+% - the d3d9 backend, on Windows, clamps the value of the COLORX semantics before passing it to
+%   the pixel shader, so their values must be between 0.0 and 1.0.
