Previously it would only accept a string as a GCC version if it had
either two components and no suffix, or three components with an
optional suffix.
Debian and ubuntu provided mingw compilers have lib/gcc/target entries
like "5.3-posix" and "5.3-win32". This doesn't try to make any specific
preference between them (other than lexical sorting of the suffix).

This makes it consistent with libstdc++ and the other default
include directories.
If these headers are found in both locations and one isn't a
symlink to the other, this will cause errors due to libc++ headers
having wrapper headers for some standard C headers, wrappers that
do #include_next the actual one.
If the same libc++ standard C wrapper header exists in more than one
include directory before the real system one, the header include
guard will stop it from doing another #include_next to pick up the
real one, breaking things.
As this is a rather uncommon situation, this should be acceptable
and toolchain maintainers can adapt accordingly if necessary.
Also simplify some of the existing code with a local variable.

This patch introduces a new cmake variable: CLANG_DEFAULT_RTLIB, thru
which we can specify a default value for -rtlib (libgcc or
compiler-rt) at build time, just like how we set the default C++
stdlib thru CLANG_DEFAULT_CXX_STDLIB.
With these two options, we can configure clang to build binaries on
Linux that have no runtime dependence on any gcc libs (libstdc++ or
libgcc_s).

Summary:
There are a number of files in the tree which have been accidentally checked in with DOS line endings. Convert these to native line endings.
There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.

Summary:
When we want to use mingw-w64 and clang with compiler-rt we should not
need to have libgcc installed. This fixes finding includes when libgcc
is not installed

Address Richard Smith comments: remove the trailing seperator from the Arch
variable, implement six mingw_* trees under tools/clangtest/Driver/Inputs
and merge linux and Windows tests into a universal test that uses these trees.
