* Attempt to better categorize PTX.

* Work around for potentially unused function warning.

* Typo fix.

* Simplify Artifact header.

* Small improvements around Artifact kind/payload/style.

* Added IDestroyable/ICastable

* Add IArtifactList.

* First impl of IArtifactUtil.

* Use the ICastable interface for IArtifactRepresentation.

* Added IArtifactRepresentation & IArtifactAssociated.

* Add SLANG_OVERRIDE to avoid gcc/clang warning.

* Fix calling convention issue on win32.

* Fix missing SLANG_OVERRIDE.

* First attempt at file abstraction around Artifact.

* Added creation of lock file.

* Move functionality for determining file paths to the IArtifactUtil.
Add casting to ICastable.

* Added some casting/finding mechanisms.

* Simplify IArtifact interface, and use Items for file reps.

* Fix problem with libraries on DXIL.

* Make our ISlangBlobs also derive from ICastable.
Make ISlangBlob atomic ref counted.

* Split out CastableList and related types, and placed in core.

* Small fixes around IArtifact.
Improve IArtifact docs.
First impl of getChildren for IArtifact.

* Documentation improvements for Artifact related types.

* Fix typo.

* Special case adding a ICastableList to a LazyCastableList.

* Small simplification of LazyCastableList, by adding State member.

* Removed the ILockFile interface because IFileArtifactRepresentation can be used.

* Implement DiagnosticsArtifactRepresentation.

* Added PostEmitMetadataArtifactRepresentation

* Add searching by predicate.
Added handling of accessing Artifact as ISharedLibrary

* Fix typo.

* Add find to IArtifacgtList.
Fix some missing SLANG_NO_THROW.

* Small improvements around ArtifactDesc types.

* Another small change around ArtifactKind.

* Some more shuffling of ArtifactDesc.

* Make IArtifact castable
Remove IArtifactList
Made IArtifactContainer derive from IArtifact
Made ModuleLibrary atomic ref counted/given IModuleLibrary interface.

* Must call _requireChildren before any children access.

* Fix missing SLANG_MCALL on castAs.

* Fix missing SLANG_OVERRIDE.
