Its a dependency for Foundation and already a dependency for the Swift
Compiler. Also part of Linux and POSIX.

fixed indentation for CUUID module map

Added validation test for CUUID

…present

Added test cases for expected-errors and validating that suggested fix works.

The rules for 'fileprivate' (the old 'private') and the rules for
the new "scoped" 'private' are the same.

LD_LIBRARY_PATH is one of the few environment variables the LLVM 'lit'
tool /doesn't/ strip out, presumably because on some Linux systems
it's necessary to run some of the built products being tested.
However, the Swift driver also uses LD_LIBRARY_PATH when providing -L
options to the script interpreter on Linux. Weaken some of our tests
when there's an LD_LIBRARY_PATH in the environment.

(There are similar environment variables on OS X, but we don't have to
do anything special there because lit /does/ strip those out. This is
presumably okay because all of LLVM's load-time dependencies on OS X
are in standard system locations.)

gold only supports ELF.  This adds two new helper functions
(is_windows_based_sdk and is_elfish_sdk) to ensure that we dont try to use gold
on non-ELF targets.  This comes up when trying to setup cross-compilation for
the standard library for Windows.

The ELF check is implemented as the negation of Darwin (which uses MachO) and
Windows (which uses COFF).  The reason for this is that there are additional
targets which also use ELF.  Rather than enumerating the larger set, enumerate
the smaller set (windows) and use the negation.

So that we can easily invoke manual testing:

cmake --build ${SWIFT_BUILD_DIR} -- upload-stdlib-{variant}
python ${LLVM_SOURCE_DIR}/utils/lit/lit.py -sv ${TEST_PATH}

These functions are not XPC-specific and can be treated as part of the
common implementation.

Python's builtin set uses intersection not intersect.

llvm/Support/Compiler.h recently grew a dependency on llvm-config.h.  This
pointed out that we were not including the path to the generated header
directory in the build output.  Ensure that we have the corresponding -I.
