Add a test for clang_rt support on Darwin. With appropriate massaging, this
checks that the runtime library can be linked and works for compiling on 10.6
for 10.{4,5,6} targets. Currently test is only for x86, and misses some
compiler-rt functions.

/* This file tests that we can succesfully call each compiler-rt function. It is
|
||||
designed to check that the runtime libraries are available for linking and
|
||||
that they contain the expected contents. It is not designed to test the
|
||||
correctness of the individual functions in compiler-rt.
|
||||
|
||||
This test is assumed to be run on a 10.6 machine. The two environment
|
||||
variables below should be set to 10.4 and 10.5 machines which can be directly
|
||||
ssh/rsync'd to in order to actually test the executables can run on the
|
||||
desired targets.
