Ulrich Weigand ac37755c60 [SystemZ] Use fneg in test cases
Now that we have fneg, prefer using it over "fsub -0.0, ...".
This helps in particular with strict FP tests, as fneg does
not raise any exceptions.

Ulrich Weigand 33435c4c9c [SystemZ] Add support for IBM z14 processor (2/3)
This adds support for the new 32-bit vector float instructions of z14.
This includes:
- Enabling the instructions for the assembler/disassembler.
- CodeGen for the instructions, including new LLVM intrinsics.
- Scheduler description support for the instructions.
- Update to the vector cost function calculations.

In general, CodeGen support for the new v4f32 instructions closely
matches support for the existing v2f64 instructions.
