[SystemZ] Start adding z196 and zEC12 support

This first step just adds definitions for SLLK, SRLK and SRAK.
The next patch will actually make use of them during codegen.

insn-bad.s tests that some form of error is reported when using these
instructions on z10.  More work is needed to get the "instruction requires:
distinct-ops" that we'd ideally like, so I've stubbed that part out for now.
I'll come back and make it mandatory once the necessary changes are in.

[SystemZ] Use SLLK, SRLK and SRAK for codegen

This patch uses the instructions added in r186680 for codegen.

ARM: Add instruction aliases for the Thumb2 PLD/PLDW (literal) alternate form.

See A8.8.127 in ARM DDI 0406C.b.

[SystemZ] Add NRK, ORK and XRK

The atomic tests assume the two-operand forms, so I've restricted them to z10.

Running and-01.ll, or-01.ll and xor-01.ll for z196 as well as z10 shows why
using convertToThreeAddress() is better than exposing the three-operand forms
first and then converting back to two operands where possible (which is what
I'd originally tried).  Using the three-operand form first stops us from
taking advantage of NG, OG and XG for spills.

[SystemZ] Add NGRK, OGRK and XGRK

Like r186683, but for 64 bits.

[SystemZ] Add ARK, AGRK, SRK and SGRK

The testsuite changes follow the same lines as for r186683.

[SystemZ] Add AHIK and AGHIK

I did these as a separate patch because it uses a slightly different
form of RIE layout.

[SystemZ] Add ALRK, AGLRK, SLRK and SGLRK

Follows the same lines as r186686, but much more limited, since we only
use ADD LOGICAL for multi-i64 additions.

[SystemZ] Add tests for ALHSIK and ALGHSIK

The insn definitions themselves crept into r186689, sorry.
This should be the last of the distinct-ops instructions.

Add a line that got missed off somehow. Sorry about that!

lit: Support cancellation on Windows

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.

[Option] Add inclusion and exclusion flags to option parsing

Summary:
This allows the clang driver to put MSVC compatible options in the same
enumerator space as its normal options but exclude them from normal
option parsing.

Also changes the standard ParseArgs() method to consider unknown
arguments with a leading slash as being inputs rather than flags.

s/compiler_used/compiler.used/.

We were incorrectly using compiler_used instead of compiler.used. Unfortunately
the passes using the broken name had tests also using the broken name.
