Frontend: Default to creating output files using temporary files + rename.
- This is a more reliable default, as it behaves better on failure and also
ensures that we create *new* files (instead of reusing existing inodes). This
is useful for other applications (like lldb) which want to cache inode's to
know when a file has been rewritten.

Introduce module attributes into the module map grammar, along with a
single attribute ("system") that allows us to mark a module as being a
"system" module. Each of the headers that makes up a system module is
considered to be a system header, so that we (for example) suppress
warnings there.

If a module is being inferred for a framework, and that framework
directory is within a system frameworks directory, infer it as a
system framework.

Detect when mapping a #include/#import over to a submodule ends up
hitting a submodule that was never actually created, e.g., because
that header wasn't parsed. In such cases, complain (because the
module's umbrella headers don't cover everything) and fall back to
including the header.

Later, we'll add a warning at module-build time to catch all such
cases. However, this fallback is important to eliminate assertions in
the ASTWriter when this happens.
