6dd41f44db ABI checker: exclude unavailable decls from ABI descriptors 
Framework authors usually have different schemes for different deployment
targets. We should exclude platform-unavailable ABIs from the Json file so
developers will only be warned of the breakages that are relevant to the current
scheme.

7b445c3c98 api-digester: keep track of the introduced platforms and language versions for all APIs 
These fields will be used to diagnose the missing of available
attributes for newly added APIs.

747d9dfe3b swift-api-digester: add a field to indicate whether a decl or a conformance is ABI placeholder. 
ABI placeholders are decls with attribute '@available(macOS 9999, iOS
9999, tvOS 9999, watchOS 9999, *)'. The diagnostics phase could be
forgiving for ABI breakages on these decls since they are added
recently. This patch adds a new flag to the json file indicating whether
a declaration or a conformance is an ABI placeholder. The checking of
placeholder is transitive, meaning a decl is an ABI placeholder if its
decl context is one.

588391eb7e swift-api-digester: avoid synthesizing nominal types from the same module. 
Synthesizing types from the same module may bring back types that are
not part the ABI/API, leading to false positives.

da4fc05a0e swift-module-digester: model ProcotolConformance as a standalone node. 
Modeling ProtocolConformance as a standalone node allows us to keep
track of all type witnesses and re-use existing matching algorithm
to diagnose type witness changes.

3f58f1e6d3 swift-module-digester: add a flag to include Swift decls specifically. 
This flag allows us to diagnose the overlay part exclusively without digesting
the entire SDK framework.

This allows us to map back from a type to the declaration in the dump,

has been changed to string enum.

1aa7816956 swift-api-digester: teach the tool to serialize and de-serialize generic requirements. 
The tool should diagnose the change of extension's applicability since
such change can be source-breaking. We need first to support the
requirements in the module dump. Currently, we decorate each
member defined in extension with a field called extension info. The
field will keep track of the generic requirements that need to be satisfied
for this decorated member to be applicable. This patch doesn't implement the checking
of requirements change.
