[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.

[ARMv8] Implement the NEON instructions VRINT{N, X, A, Z, M, P}.

[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!
