39bb7bfe44 [AST] Convert ASTContext::getSwiftName to a free function 
The only state `getSwiftName` uses is its argument, and can be made a free function. Of
note the inverse operation, `getKnownFoundationEntity`, is also a free function. This
removes the requirement that callers have an `ASTContext` instance.

(cherry-picked from commit fb524c0b86)

cfb3e5abae Reintroduce alwaysinline and nodebug as fallbacks to SWIFT_INLINE_THUNK_ATTRIBUTES 
If the C++ compiler doesn't support the transparent_stepping attribute,
fallback to annotating inline thunks with the alwaysinline and nodebug
attributes.

7c8523cfec Use "transparent_stepping" attribute in C++ compiler generated interop 
Use transparent_stepping instead of nodebug and alwaysinline in compiler
generated C++ code from Swift. This attribute allow for annotated
functions to be used in expression evaluation, which is an advantage
over the former two.

4fda7f4a9a [interop][SwiftToCxx] do not expose APIs with imported declarations whose modules do not have a generated header as specified by the user 
The frontend option '-clang-header-expose-module' allows the user to specify that APIs from an imported module have been exposed in another generated header, and thus APIs that depend on them can be safely exposed in the current generated header.

0e932329c3 Fix fulfillments for type metadata and witness table packs 
A lot of the fixes here are adjustments to compensate in the
fulfillment and metadata-path subsystems for the recent pack
substitutions representation change.  I think these adjustments
really make the case for why the change was the right one to make:
the code was clearly not considering the possibility of packs
in these positions, and the need to handle packs makes everything
work out much more cleanly.

There's still some work that needs to happen around type packs;
in particular, we're not caching them or fulfilling them as a
whole, and we do have the setup to do that properly now.

1629521b12 Exclude @objcImpl member impls from PrintAsObjC 
PrintAsClang was not aware of @objcImplementation. Teach it to skip over both member implementations (which are declared in handwritten headers, so printing them would be a redeclaration) and overrides (which may not be valid in a category, if e.g. they are declaring a designated initializer).

Fixes rdar://106035578.

3948a2a5d3 [interop][SwiftToCxx] annotate inline thunks with SWIFT_INLINE_THUNK 
This macro applies always_inline in addition to inline. It also applies artificial, which lets debugger know that this is an artificial function. The used attribute is added in debug builds to ensure that the symbol is emitted in the binary so that LLDB can invoke it.
