eb90e83085 Store the submodules of a module in source order, as they are stored
in the module map. This provides a bit more predictability for the
user, as well as eliminating the need to sort the submodules when
serializing them.

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).

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.

73141fa98d Within the module representation, generalize the notion of an umbrella
header to also support umbrella directories. The umbrella directory
for an umbrella header is the directory in which the umbrella header
resides.

No functionality change yet, but it's coming.

734410916a Parse inferred submodules in module maps, track their contents in
Module, and (de-)serialize this information. Semantics of inferred
submodules to follow.

f5eedd05db Implement support for wildcard exports in modules, allowing a module
to re-export anything that it imports. This opt-in feature makes a
module behave more like a header, because it can be used to re-export
the transitive closure of a (sub)module's dependencies.

module map.

de3ef502a9 Promote ModuleMap::Module to a namespace-scope class in the Basic
library, since modules cut across all of the libraries. Rename
serialization::Module to serialization::ModuleFile to side-step the
annoying naming conflict. Prune a bunch of ModuleMap.h includes that
are no longer needed (most files only needed the Module type).
