* Adds support for pause/resume in pipeline.
* Adds 0.0 as the validator version to indicate no validation should occur.
* Moves module parsing from dxcompiler down to HLSL library.
* Adds support for optimizer to process a DXIL part.
* Adds a form with designer support for the interactive optimizer.
* Fix ViewID state for flow control and consistent ViewID detection
1. Different ways of determining ViewID usage led to assert or crash.
Use DxilModule flag to guarantee consistency. But this required
splitting DxilEmitMetadata pass into two passes, one that finalizes
the module and computes flags run before ComputeViewIdState, and one
that simply writes the metadata.
2. storeOutput in flow control with values not dependent on that flow,
such as literals, would not pick up control flow dependence.
Fix by picking up control flow dependence on storeOutput instructions,
not just the value being written.
* Fix control depenence computation
There was a bug in the implementation of the control dependence algorithm.
We were incorrectly iterating over all descendents in the postdom tree where
the algorithm should only iterate over immediate children.
This change is to support preserve denorm operations. We do this by creating dxc options and propagate them all the way to dxil metadata so that drivers can see how it should handle floats.
Currently we support three modes: any(default), preserve, and ftz
Denorm option will be of per function flag. We store this information at function annotation metadata. This means that for DXIL 1.2 we have a new structure for function annotation. The change in structure is documented on DXIL.rst
