Add an explicit API to read the Xcode SDK DWARF attribute from compile units

Authored by aprantl on May 1 2020, 3:56 PM.



When debugging from a SymbolMap the creation of CompileUnits for the
individual object files is so lazy that RegisterXcodeSDK() is not invoked at all
before the Swift TypeSystem wants to read it. This patch fixes this by
introducing an explicit SymbolFile::ParseXcodeSDK() call that can be
invoked deterministically before the result is required.

Delete more code that is made obsolete by the new API.

This looks good to me. If a similar API made sense on Module, I guess it can live on SymboleFile.
