Ben Langmuir beee15e721 Allow multiple modules with the same name to coexist in the module cache 
To differentiate between two modules with the same name, we will
consider the path the module map file that they are defined by* part of
the ‘key’ for looking up the precompiled module (pcm file).
Specifically, this patch renames the precompiled module (pcm) files from
  cache-path/<module hash>/Foo.pcm
to
  cache-path/<module hash>/Foo-<hash of module map path>.pcm

In addition, I’ve taught the ASTReader to re-resolve the names of
imported modules during module loading so that if the header search
context changes between when a module was originally built and when it
is loaded we can rebuild it if necessary.  For example, if module A
imports module B

first time:
clang -I /path/to/A -I /path/to/B ...

second time:
clang -I /path/to/A -I /different/path/to/B ...

will now rebuild A as expected.

* in the case of inferred modules, we use the module map file that
allowed the inference, not the __inferred_module.map file, since the
inferred file path is the same for every inferred module.

Douglas Gregor 35b04d6fd2 Rename -fmodule-cache-path <blah> to -fmodules-cache-path=<blah> for consistency.

Douglas Gregor c50d4924eb Use @import rather than @__experimental_modules_import, since the 
latter is rather a mess to type.
