or directories, to make sure that they are identifiers that are not
keywords in any dialect. Fixes <rdar://problem/12489495>.

umbrella headers in the sense that all of the headers within that
directory (and eventually its subdirectories) are considered to be
part of the module with that umbrella directory. However, unlike
umbrella headers, which are expected to include all of the headers
within their subdirectories, Clang will automatically include all of
the headers it finds in the named subdirectory.
The intent here is to allow a module map to trivially turn a
subdirectory into a module, where the module's structure can mimic the
directory structure.

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.

the umbrella header's directory and its subdirectories are part of the
module (that's why it's an umbrella). Make sure that these headers are
considered to be part of the module for lookup purposes.

into a submodule. Submodules aren't actually supported anywhere else,
but we do parse them, so this verifies that we're at least seeing
through them properly.

the module is described in one of the module maps in a search path or
in a subdirectory off the search path that has the same name as the
module we're looking for.

map, so long as they have an umbrella header. This makes it possible
to introduce a module map + umbrella header for a given set of
headers, to turn it into a module.
There are two major deficiencies here: first, we don't go hunting for
module map files when we just see a module import (so we won't know
about the modules described therein). Second, we don't yet have a way
to build modules that don't have umbrella headers, or have incomplete
umbrella headers.

Module map files provide a way to map between headers and modules, so
that we can layer a module system on top of existing headers without
changing those headers at all.
This commit introduces the module map file parser and the module map
that it generates, and wires up the module map file parser so that
we'll automatically find module map files as part of header
search. Note that we don't yet use the information stored in the
module map.
