Link.exe's command line options are case-insensitive. This patch
adds a new attribute to OptTable to let the option parser to compare
options, ignoring case.
Command lines are generally case-insensitive on Windows. CL.exe is an
exception. So this new attribute should be useful for other commands
running on Windows.

This function attribute indicates that the function is not optimized
by any optimization or code generator passes with the
exception of interprocedural optimization passes.

This field specifies registers that are preserved across function calls,
but that should not be included in the generates SaveList array.
This can be used ot generate regmasks for architectures that save
registers through other means, like SPARC's register windows.

Back in the mists of time (2008), it seems TableGen couldn't handle the
patterns necessary to match ARM's CMOV node that we convert select operations
to, so we wrote a lot of fairly hairy C++ to do it for us.
TableGen can deal with it now: there were a few minor differences to CodeGen
(see tests), but nothing obviously worse that I could see, so we should
probably address anything that *does* come up in a localised manner.

- For whatever reason, we have a lot of test files with bogus unicode
characters. This patch allows those scripts to still be parsed on Python3 by
changing the parsing logic to work on binary files, and only require the
actual script commands to be convertible to ascii.
- This patch has been tweaked to now ensure that the command strings are not of
unicode type on Python 2.6-7.

- We barely used it, and it is very hard to use in a 2.5-3 compatible
way because of changing expectations for its input types.

FileCheck should check to make sure the prefix was found, and not a word
containing it (e.g -check-prefix=BASEREL shouldn't match NOBASEREL).

clang bootstraps intermittently failed for me due a difference in
the MCK_Reg ordering in ARMGenAsmMatcher.inc. E.g. in my latest
run the stage 1 and stage 3 versions were the same but the stage 2
one was different (though still functionally correct). This meant
that the .o comparison failed.
MCK_Regs were assigned by iterating over a std::set< std::set<Record*> >,
and since std::set is sorted lexicographically, the order depended on the
order of the pointer values. This patch replaces the pointer ordering
with LessRecordByID.

- Injecting it as 'lit' is gross, since that name should be used to refer to
the actual package. For now both are available so it is possibly to cleanup
test config files incrementally.

- 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.

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.
