Richard Smith 7e82e019c6 [modules] Flatten -fmodule-name= and -fmodule-implementation-of= into a single
option. Previously these options could both be used to specify that you were
compiling the implementation file of a module, with a different set of minor
bugs in each case.

This change removes -fmodule-implementation-of, and instead tracks a flag to
determine whether we're currently building a module. -fmodule-name now behaves
the same way that -fmodule-implementation-of previously did.

Juergen Ributzka 8aaae5a911 Fix auto-link for text-based dynamic library SDKs.
When linking against text-based dynamic library SDKs the library name of a
framework has now more than one possible filename extensions. This fix tests for
both possible extensions (none, and .tbd).

This fixes rdar://problem/20609975

Sean Silva 8b7c0398b6 [modules] PR20507: Avoid silent textual inclusion.
Summary:
If a module was unavailable (either a missing requirement on the module
being imported, or a missing file anywhere in the top-level module (and
not dominated by an unsatisfied `requires`)), we would silently treat
inclusions as textual. This would cause all manner of crazy and
confusing errors (and would also silently "work" sometimes, making the
problem difficult to track down).

I'm really not a fan of the `M->isAvailable(getLangOpts(), getTargetInfo(),
Requirement, MissingHeader)` function; it seems to do too many things at
once, but for now I've done things in a sort of awkward way.

The changes to test/Modules/Inputs/declare-use/module.map
were necessitated because the thing that was meant to be tested there
(introduced in r197805) was predicated on silently falling back to textual
inclusion, which we no longer do.

The changes to test/Modules/Inputs/macro-reexport/module.modulemap
are just an overlooked missing header that seems to have been missing since
this code was committed (r213922), which is now caught.

Ben Langmuir 7ff29148ac [Modules] Add Darwin-specific compatibility module map parsing hacks
This preserves backwards compatibility for two hacks in the Darwin
system module map files:

1. The use of 'requires excluded' to make headers non-modular, which
should really be mapped to 'textual' now that we have this feature.

2. Silently removes a bogus cplusplus requirement from IOKit.avc.

Once we start diagnosing missing requirements and headers on
auto-imports these would have broken compatibility with existing Darwin
SDKs.

Ben Langmuir a525400d37 [Modules] Be consistent about finding a module for framework headers
We use findModuleForHeader() in several places, but in header search we
were not calling it when a framework module didn't show up with the
expected name, which would then lead to unexpected non-modular includes.
Now we will find the module unconditionally for frameworks.  For regular
frameworks, we use the spelling of the module name from the module map
file, and for inferred ones we use the canonical directory name.

In the future we might want to lock down framework modules sufficiently
that these name mismatches cannot happen.

Richard Smith 47972afd10 [modules] Simplify -cc1 interface for enabling implicit module maps.
We used to have a flag to enable module maps, and two more flags to enable
implicit module maps. This is all redundant; we don't need any flag for
enabling module maps in the abstract, and we don't usually have -fno- flags for
-cc1. We now have just a single flag, -fimplicit-module-maps, that enables
implicitly searching the file system for module map files and loading them.

The driver interface is unchanged for now. We should probably rename
-fmodule-maps to -fimplicit-module-maps at some point.

Richard Smith 4241314164 [modules] Add local submodule visibility support for declarations.
With this change, enabling -fmodules-local-submodule-visibility results in name
visibility rules being applied to submodules of the current module in addition
to imported modules (that is, names no longer "leak" between submodules of the
same top-level module). This also makes it much safer to textually include a
non-modular library into a module: each submodule that textually includes that
library will get its own "copy" of that library, and so the library becomes
visible no matter which including submodule you import.

Yaron Keren 92e1b62d45 Remove many superfluous SmallString::str() calls.
Now that SmallString is a first-class citizen, most SmallString::str()
calls are not required. This patch removes a whole bunch of them, yet
there are lots more.

There are two use cases where str() is really needed:
1) To use one of StringRef member functions which is not available in
SmallString.
2) To convert to std::string, as StringRef implicitly converts while 
SmallString do not. We may wish to change this, but it may introduce
ambiguity.

Richard Smith 9acb99e342 Reinstate r223753, reverted in r223759 due to breakage of clang-tools-extra.
Original commit message:

[modules] Add experimental -fmodule-map-file-home-is-cwd flag to -cc1.

For files named by -fmodule-map-file=, and files found by 'extern module'
directives, this flag specifies that we should resolve filenames relative to
the current working directory rather than relative to the directory in which
the module map file resides. This is aimed at fixing path handling, in
particular for relative -I paths, when building modules that represent
components of the current project (rather than libraries installed on the
current system, which the current project has as dependencies, where we'd
typically expect the module map files to be looked up implicitly).

but I'm not the right one to look into it.

Richard Smith 3c1a41ad99 [modules] Track how 'header' directives were written in module map files,
rather than trying to extract this information from the FileEntry after the
fact.

This has a number of beneficial effects. For instance, diagnostic messages for
failed module builds give a path relative to the "module root" rather than an
absolute file path, and the contents of the module includes file is no longer
dependent on what files the including TU happened to inspect prior to
triggering the module build.

Richard Smith 306d892076 [modules] Add support for 'textual header' directives.

Richard Smith 25d50758f3 [modules] Add support for #include_next.
#include_next interacts poorly with modules: it depends on where in the list of
include paths the current file was found. Files covered by module maps are not
found in include search paths when building the module (and are not found in
include search paths when @importing the module either), so this isn't really
meaningful. Instead, we fake up the result that #include_next *should* have
given: find the first path that would have resulted in the given file being
picked, and search from there onwards.

We already verified the primary module map file (either the one that

map files that define submodules, such as when there is a
module.private.modulemap file.

the remaining cases.  This lets us do less bookkeeping to keep the
