This allows modules to opt into import-as-member's inference system. Includes the attribute itself and APINotes support.

[Import as member] Module map attribute swift_infer_import_as_member
6eae124 
Introduces a new module map attribute, allowing a module to opt-into
import-as-member inference. This allows the provider of the APIs to
use inference, rather than require building with a flag.
@milseman
[Import as member] APINotes for SwiftInferImportAsMember.
6e75259 
Adds APINotes support for adding the swift_infer_import_as_member
module map attribute.

[APINotes] Apply ModuleOptions
d05e46e 
CompilerInstance will now check for ModuleOptions in the current
module's APINotes, and apply them if present.

Doesn't seem like @swift-ci is capable of testing Clang merges. This passes Clang's lit test suite locally for me.

@DougGregor , care to comment?

A few comments. Also, remember to commit this to upstream-with-swift and cherry-pick into stable/stable-next.

@gottesmm This has gone into upstream-with-swift and stable. Do you want this to also go into stable-next?

Can you also put it into swift-3.0-branch as well.

@milseman The need to cherry-pick in so many places will go away this weekend (I am finishing up an email right now that elaborates on this).

@gottesmm I pushed to swift-3.0-branch. I have not pushed to stable-next, do I need to?

Remove a useless assertion in clang-check.

The assertion prevents it from applying fixes when used along with compilation
databases with relative paths. Added a test that demonstrates the assertion
failure.

The assertion prevents it from applying fixes when used along with compilation
databases with relative paths. Added a test that demonstrates the assertion
failure.

An example of the assertion:
