* [ClangImporter] Remove importer-based NS stripping.
As Tony puts it, in the end we wound up with more Foundation
declarations imported as members or keeping "NS" than those that
dropped it, and any further decisions will be made on a case-by-case
basis. Move all of the existing cases of prefix-stripping into
Foundation's API notes and drop the logic from the compiler.
Tested by dumping the generated interface for Foundation and its
submodules for both macOS and the iOS simulator, and comparing the
results. A few cases did slip through here because of the interaction
between "SwiftName" and "Availability: nonswift".
The next commit will re-add "NS" to some stragglers that we missed.

* APINotes: Add "NS" back to a few types.
NSKeyedUnarchiverDelegate
NSKeyedArchiverDelegate
NSTextCheckingTypes
NSBinarySearchingOptions
NSEnumerationOptions
NSSortOptions

* Remove now-redundant SwiftNames from API notes.
No change observed in the generated interface of Foundation and its
submodules.

this is neutral w.r.t. diagnostics quality, but deletes a ton

if it has already resolved a member binding of an UnresolvedDotExpr. This allows
us to give tailored diagnostics to indicate whether the destination is not an lvalue
because the property itself was immutable or when the base is immutable.
In addition to improved diagnostics, this allows us to fixit hint "let" to "var" on
property definitions, and we can even go so far as to fixit hint insert 'mutating' on
the enclosing func decl when self is the problem.
This fixes the non-subscript cases of:
<rdar://problem/17632908> QoI: Modifying struct member in non-mutating function produces difficult to understand error message
<rdar://problem/19370429> QoI: fixit to add "mutating" when assigning to a member of self in a struct
<rdar://problem/20234955> QoI: Error message for assigning to 'let' fields should say that the error is due to a 'let' binding
Subscript cases to follow.
