Modules and Tooling tests in particular tend to want to change the cwd,
so we were missing test coverage in this area on Windows. It should now
be easier to write such portable tests.

one can give us more lookup results (due to implicit special members). Be sure
to complete the redecl chain for every kind of DeclContext before performing a
lookup into it, rather than only doing so for NamespaceDecls.

This is a necessary prerequisite for debugging with modules.
The .pcm files become containers that hold the serialized AST which allows
us to store debug information in the module file that can be shared by all
object files that were built importing the module.
This reapplies r230044 with a fixed configure+make build and updated
dependencies and testcase requirements. Over the last iteration this
version adds
- missing target requirements for testcases that specify an x86 triple,
- a missing clangCodeGen.a dependency to libClang.a in the make build.

This would cause frameworks to have spurious "redefinition" errors if
they had both a (legacy) "module.map" and a (new) "module.modulemap" file and we
happened to do a sub-directory search in that directory using a
non-framework include path (e.g. -Ifoo/ -Ffoo/). For migration
purposes it's very handy that the compiler will prefer the new spelling
of the filename and not look at the old one if it doesn't need to.

If this flag is set, we error out when a module build is required. This is
useful in environments where all required modules are passed via -fmodule-file.

This protects against the badness occurring from getting modules loaded from different module caches (see crashes).

entity, put the originally-canonical decl IDs in the right places in the redecl
chain rather than reordering them all to the start. If we don't ensure that the
redecl chain order is consistent with the topological module order, we can fail
to make a declaration visible if later declarations are in more IDNSs than
earlier ones (for instance, because the earlier decls are invisible friends).

When mangling the module map path into a .pcm file name, also mangle the
IsSystem bit, which can also depend on the header search paths. For
example, the user may change from -I to -isystem. This can affect
diagnostics in the importing TU.

existing declaration. If it isn't, we might (say) replace a visible declaration
with an injected friend, and thus make it invisible (or lose a default argument
or an array bound).

of that entity, ensure that the redeclaration chain is reordered properly on
reload. Otherwise, the result of name lookup for that entity may point to an
entity that is too old; if that's an injected friend name or the like, that
can result in the name not being found at all.

object. In such a case, use the TU's DC for merging global decls rather than
giving up when we find there is no TU scope.
Ultimately, we should probably avoid all loading of decls when preprocessing,
but there are other reasonable use cases for loading an AST file with no Sema
object for which this is the right thing.
