This reflects the common use case of nativizing a prepared path. The existing
version invokes undefined behavior if input = output, add an assert to catch
that case.

With r190382, -Wunused-variable warns about unused const variables when
appropriate. For codebases that use -Werror, this poses a problem as
existing unused const variables need to be cleaned up first. To make the
transistion easier, this patch splits -Wunused-variable by pulling out
an additional -Wunused-const-variable (by default activated along with
-Wunused-variable).

This patch is the first step to make module-map-files modular (instead
of requiring a single "module.map"-file per include directory). This
step adds a new "extern module" declaration that enables
module-map-files to reference one another along with a very basic
implementation.
The next steps are:
* Combine this with the use-declaration (from
http://llvm-reviews.chandlerc.com/D1546) in order to only load module
map files required for a specific compilation.
* Add an additional flag to start with a specific module-map-file (instead
of requiring there to be at least one "module.map").

Summary:
More accurately characterize the nature of array parameters. Doing this
removes false back-reference opportunities. Remove some hacks now that
we characterize these better.

non-member function, the number of arguments in the two candidate calls
will be different (the non-member call will have one extra argument).
We used to get confused by this, and fail to compare the last argument
when testing whether the member is better, resulting in us always
thinking it is, even if the non-member is more specialized in the last
argument.

YAMLIO printed a string as is without quotes unless it contains a newline
character. That did not suffice. We also need to quote a string if it starts
with a backquote, quote, double quote or atsign, or it's the empty string.

Some build systems use pipes for stdin/stderr. On nix-ish platforms colored
output can be forced by -fcolor-diagnostics. On Windows this option has
no effect in these cases because LLVM uses the console API (which only
operates on the console buffer) even if a console wrapper capable of
interpreting ANSI escape codes is used.
The -fansi-escape-codes option allows switching from the console API to
ANSI escape codes. It has no effect on other platforms.

In some cases (e.g. when a build system pipes stderr) the Windows console
API cannot be used to color output. For these, provide a way to switch to
ANSI escape codes. This is required for Clang's -fansi-escape-codes option.
