When a resource is accessed, it is now tracked by the debug step. The
shader viewer has a new panel to display resources accessed up to the
current step, with context menus to go to previous/next access of a
specific resource.
When getting read only resources from the pipe state, stitch back up
according to the bindpoint mappings. When displaying resources in UI,
don't traverse unbounded arrays. Fix resource swizzle on load/sample/
gather instructions, which happens on fetch result, not on the source
operand. Added more tests for unbounded arrays and different ways to
index into arrays.
The logical identifiers, rather than shader registers, were used to
populate reflection info, causing the wrong slots in large descriptor
tables to be referenced for the pipeline state.
