Jessica Paquette af0b0f857f [GlobalISel][AArch64] Add isel support for FP16 vector @llvm.ceil 
This patch adds support for vector @llvm.ceil intrinsics when full 16 bit
floating point support isn't available.

To do this, this patch...

- Implements basic isel for G_UNMERGE_VALUES
- Teaches the legalizer about 16 bit floats
- Teaches AArch64RegisterBankInfo to respect floating point registers on
  G_BUILD_VECTOR and G_UNMERGE_VALUES
- Teaches selectCopy about 16-bit floating point vectors

It also adds

- A legalizer test for the 16-bit vector ceil which verifies that we create a
  G_UNMERGE_VALUES and G_BUILD_VECTOR when full fp16 isn't supported
- An instruction selection test which makes sure we lower to G_FCEIL when
  full fp16 is supported
- A test for selecting G_UNMERGE_VALUES

And also updates arm64-vfloatintrinsics.ll to show that the new ceiling types
work as expected.

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
