Add a callback for `__has_include` and use it for dependency scanning. This adds a preprocessor callback for the `__has_include` and `__has_include_next` directives. Successful checking for the presence of a header should add it to the list of header dependencies so this overrides the callback in the dependency scanner. Patch by Pete Cooper with some additions by me. rdar://problem/39545636 Differential Revision: https://reviews.llvm.org/D30882 llvm-svn: 342517

Re-land Remove REQUIRES:shell from tests that pass for me on Windows This reverts r371497 (git commit 3d7e9ab7b9f8c53aa41420c54970f0fb421004a2) Reorder `not` with `env` in these two tests so they pass: Driver/rewrite-map-in-diagnostics.c Index/crash-recovery-modules.m. This will not be necessary after D66531 lands. llvm-svn: 371552
