c++: Quoting in -fmodules-mapper

Users might be using a space in their build directory path. To allow
specifying such a root for the module mapper started by GCC, we need the
command to allow quotes. Previously quoting a path passed to the module
mapper was not possible, so replace the custom argv parsing with
the argv parsing logic from libiberty, that supports fairly standard
shell quoting using single and double quotes.

The primary purpose of this patch is to allow passing paths with spaces
to the --root parameter of the module mapper.

No test is included as spaces in build directories are tricky cross
platform. The patch was tested manually on my system.
