Eric Fiselier e38cea026b [coroutines] Support "coroutines" feature in module map requires clause
Summary: In order for libc++ to add `<experimental/coroutine>` to its module map, there has to be a feature that can be used to detect if coroutines support is enabled in Clang.

Ben Langmuir 532d2104ce Add cc1 option '-fmodule-feature' to add custom values for 'requires' decls
This allows clang-based tools to specify custom features that can be
tested by the 'requires' declaration in a module map file.

Richard Smith a3feee2ad6 Allow a new syntax in a module requires-declaration:
requires ! feature

The purpose of this is to allow (for instance) the module map for /usr/include
to exclude <tgmath.h> and <complex.h> when building in C++ (these headers are
instead provided by the C++ standard library in this case, and the glibc C
<tgmath.h> header would otherwise try to include <complex.h>, resulting in a
module cycle).

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

Douglas Gregor 0bf886d41a Under -fmodules, accept #public <macroname> and #private <macroname>
to make a macro public (the default for headers) or private,
respectively.

Douglas Gregor 1fb5c3a63a Implement support for module requirements, which indicate the language
features needed for a particular module to be available. This allows
mixed-language modules, where certain headers only work under some
language variants (e.g., in C++, std.tuple might only be available in
C++11 mode).

Douglas Gregor 322f633c1c Tweak the syntax of umbrella headers, so that "umbrella" is treated as
a modifier for a header declarartion, e.g.,

  umbrella header "headername"

Collapse the umbrella-handling code in the parser into the
header-handling code, so we don't duplicate the header-search logic.

Douglas Gregor e7ab36693b Implement basic support for private headers in frameworks. In essence,
when we load a module map (module.map) from a directory, also load a
private module map (module_private.map) for that directory, if
present. That private module map can inject a new submodule that
captures private headers.

Douglas Gregor f2161a70aa Implement modules support for subframeworks (aka embedded
frameworks). A submodule can now be labeled as a "framework", and
header search will look into the appropriate Headers/PrivateHeaders
subdirectories for named headers.

modules (obviously) describe frameworks, and understand the header
layout of frameworks.
