Bind Location (#1166)

* First pass at BindLocation.

* Added BindSet::init - for initializing with two input constant buffers. Needs better name, and perhaps should be another class.

* Fix handling of constant buffer stripping.
Improved initialization.

* Trying to generalize BindLocation a little more.
Split out CPULikeBindRoot.

* More work to make BindLocation et al work with non uniform bindings.

* Added parsing to a location.

* WIP: Trying to get CPU working with BindLocation.

* Describe problem of knowing the type of the reference point in the binding table.

* More ideas on getBindings fix.

* Remove BindSet as member of BindLocation.

* Added BindLocation::Invalid

* Made BindLocation able to be key in hash

* Use BindLocation for bindings on BindingSet.

* Added cuda and nvrtc categories to test infrastructure.
Disabled CUDA synthetic tests by default.
Fixed such that all tests now produce something in BindLocation style.

* Use m_userIndex instead of m_userData on Resource.
Move the binding setup out of cpu-compute-util (as no longer CPU specific)

* Removed CPUBinding - used BindLocation/BindSet instead.
Fixed some bugs around indexOf around uniform indirection.

* Renamed BindSet::Resource -> BindSet::Value.

* Document BindLocation.

* Fixes for Clang/GCC
Improve invariant requirement handling when constructing from BindPoints.
