kfdtest: Update shaders to compile on gfx940

gfx940 changed the semantics of the glc and slc coherency options
on vector stores and loads. This means that shaders that use
those bits no longer compile on gfx940.

Add precompilation if statements to those shaders to use the
new coherency bits.

Also add gfx940 to ASMTest so that compilation is tested.

Note: One of the tests enabled by this patch on gfx940,
KFDEvictTest.QueueTest, does not pass on gfx940 emulators.
