This change also adds proper error messages for some error/unsupported cases that weren't being diagnosed: * Specifying a completely bogus register "class" (e.g., `register(bad99)`) * Failing to specify a register index (`register(u)`) * Specifying a component mask (`register(t0.x)`) * Using `packoffset` bindings I added test cases to cover all of these, as well as the new errors around support for register `space` bindings. In order to get the existing tests to pass, I had to remove explicit `packoffset` bindings from some DXSDK test shaders. None of these `packoffset` bindings were semantically significant (they matched what the compiler would do anyway, for both Slang and the standard HLSL compiler). Removing them is required for Slang now that we give an explicit error about our lack of `packoffset` support. In a future change we might add logic to either detect semantically insignificant `packoffset`s, or to just go ahead and support them properly (as a general feature on `struct` types).
