Resources in groupshared memory causes internal compiler error

[pow2clk]

Description
Applying the groupshared qualifier onto resource globals results in an internal compiler error. This shouldn't be allowed, but it should produce a useful user error and not an internal casting failure.

Steps to Reproduce

Declare a texture and/or sampler with the groupshared qualifier and make use of them so they don't get eliminated.
