Daniel Dunbar 69e4746439 [IRgen] Update modules autolink metadata to use module flags (as now specified
in the LangRef).

Douglas Gregor c60437fb89 Add -fmodules-autolink/-fno-modules-autolink (defaults to on) so that
users can explicitly enable/disable modules autolinking.

Douglas Gregor bc25ff4661 Topologically sort the link options generated for modules based on
module-import dependencies, so we'll get the link order correct for
those silly linkers that need it.

Douglas Gregor 1715a2f9d5 When forming the link options for an imported module, also include the
link options for the modules it imports.

Douglas Gregor ea02f26536 Switch autolinking metadata format over to actual linker options, e.g.,
!0 = metadata !{metadata !"-lautolink"}
  !1 = metadata !{metadata !"-framework", metadata !"autolink_framework"}

referenced from llvm.module.linkoptions, e.g.,

  !llvm.module.linkoptions = !{!0, !1, !2, !3}

This conceptually moves the logic for figuring out the syntax the
linker will accept from LLVM into Clang. Moreover, it makes it easier
to support MSVC's

  #pragma comment(linker, "some option")

in the future, should anyone care to do so.

Douglas Gregor 11dfe6fe3d Infer "link" lines for top-level frameworks. Essentially, a framework
will have a shared library with the same name as its framework (and no
suffix!) within its .framework directory. Detect this both when
inferring the whole top-level framework and when parsing a module map.

Douglas Gregor 6ddfca91e0 Implement parsing, AST, (de-)serialization, and placeholder global
metadata for linking against the libraries/frameworks for imported
modules.

The module map language is extended with a new "link" directive that
specifies what library or framework to link against when a module is
imported, e.g.,

  link "clangAST"

or

  link framework "MyFramework"

Importing the corresponding module (or any of its submodules) will
eventually link against the named library/framework.

For now, I've added some placeholder global metadata that encodes the
imported libraries/frameworks, so that we can test that this
information gets through to the IR. The format of the data is still
under discussion.
