- Since we only have a few of these, use the cumbersome method of getting the
exception object from 'sys' to retain the current pre-2.6 compatibility.

LLVM's coding standards recommend raw_ostream and MemoryBuffer for
reading and writing text.
This has the side effect of allowing clang to compile more of Support
and TableGen in the Microsoft C++ ABI.

The clients of this code have been updated to all support AliasArgs.
This depends on Clang r187538 and lld r187541.

This makes option aliases more powerful by enabling them to
pass along arguments to the option they're aliasing.
For example, if we have a joined option "-foo=", we can now
specify a flag option "-bar" to be an alias of that, with the
argument "baz".
This is especially useful for the cl.exe compatible clang driver,
where many options are aliases. For example, this patch enables
us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to
"-Werror" (again, -W is a joined option).

This change makes test with RUN lines like
RUN: opt ... | FileCheck
fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.
Pipefail is used when the shell supports it or when using the internal
python based tester.

For two intrinsics 'llvm.nvvm.texsurf.handle' and 'llvm.nvvm.texsurf.handle.internal',
TableGen was emitting matching code like:
if (Name.startswith("llvm.nvvm.texsurf.handle")) ...
if (Name.startswith("llvm.nvvm.texsurf.handle.internal")) ...
We can never match "llvm.nvvm.texsurf.handle.internal" here because it will
always be erroneously matched by the first condition.
The fix is to sort the intrinsic names and emit them in reverse order.

This removes the need to store the asm variant in each row of the single table that existed before. Shaves ~16K off the size of X86AsmParser.o.

The current machinery using KeyboardInterrupt for canceling doesn't work
with multiple threads on Windows as it just cancels the currently run tests
but the runners continue.
We install a handler for Ctrl-C which stops the provider from providing any
more tests to the runners. Together with aborting all currently running
tests, this brings lit to a halt.

This centralizes the handling of O_BINARY and opens the way for hiding more
differences (like how open behaves with directories).
