Ethan Lee aa17d139be tests: Add a test for arrays with an expression as the index.
Currently, the compiler requires that dereferences be HLSL_IR_CONSTANT, so that
it can compute the offset at compile time. However, scenarios such as this test
will produce a dereference with HLSL_IR_EXPR, which will generate an error.

Passing this test in particular will require adding support for SM4 relative
addressing, as well as support for non-constant indexing in general.
