Ulrich Weigand 2b3482fe85 [SystemZ] Add support for IBM z14 processor (1/3)
This patch series adds support for the IBM z14 processor.  This part includes:
- Basic support for the new processor and its features.
- Support for new instructions (except vector 32-bit float and 128-bit float).
- CodeGen for new instructions, including new LLVM intrinsics.
- Scheduler description for the new processor.
- Detection of z14 as host processor.

Support for the new 32-bit vector float and 128-bit vector float
instructions is provided by separate patches.

Jonas Paulsson 4f0509fab3 [SystemZ] Correct the SchedModel regarding vector unit / instructions.
* Use a generic vector unit to model the issue unit more accurately.
* Update some vector instructions that actually use the vector unit for more
  than one cycle.

Jonas Paulsson 8010b631d5 [SystemZ] Post-RA scheduler implementation
Post-RA sched strategy and scheduling instruction annotations for z196, zEC12
and z13.

This scheduler optimizes decoder grouping and balances processor resources
(including side steering the FPd unit instructions).

The SystemZHazardRecognizer keeps track of the scheduling state, which can
be dumped with -debug-only=misched.
