Windows uses \ as the directory separator and this causes the tests to fail on
Windows.

Use a regex for the clang version as that will change all the time.

This mirrors the many other -i*after options to insert a new system search
directory at the end of the search path.  This makes it possible to actually
inject a search path after the resource dir.  This option is similar in spirit
to the /imsvc option in the clang-cl driver.  This is needed to properly use the
driver for Windows targets where the clang headers wrap some of the system
headers.

This concept is actually useful on other targets (e.g. Linux) and would be
really easy to support on the core toolchain.

This will be needed for the next commit that allows to switch the default
C++ library which would otherwise make these tests fail.

Accidentally made the test too strict.

Add the required libraries to the linker invocation when building with
sanitizers.

Indicate support for ASAN on the CrossWindows toolchain.  Although this is
insufficient, this at least permits the handling of the driver flag.

Update the linker selection to support the `-fuse-ld=` option for selecting a
linker.

Unlike Unices, Windows does not use a library prefix.  Use the traditional
naming scheme even for Windows itanium environments.  This makes the builtins
behave more like the sanitisers as well.

The option is '--allow-multiple-definition' not '--allow-multiple-definitions'.

Add a fake linker in to a sysroot to use for testing the driver's tool
invocation.  Should make the test behave similarly on all platforms.  Addresses
review comments from Reid Kleckner from SVN r220546.

I suspect it will need a custom sysroot to pass reliably elsewhere.

This is a very basic toolchain.  It supports cross-compiling Windows (primarily
inspired by the WoA target).  It is meant to use clang with the LLVM IAS and a
binutils ld-compatible interface for the linker (eventually to be lld).  It does
not perform any "standard" GCC lookup, nor does it perform any special
adjustments given that it is expected to be used in an environment where the
user is using MSVCRT (and as such Visual Studio headers) and the Windows SDK.
The primary runtime library is expected to be compiler-rt and the C++
implementation to be libc++.

It also expects that a sysroot has been setup given the usual Unix semantics
(standard C headers in /usr/include, all the import libraries available in
/usr/lib).  It also expects that an entry point stub is present in /usr/lib
(crtbegin.obj for executables, crtbeginS.obj for shared libraries).

The entry point stub is responsible for running any GNU constructors.
