[ARM] Add ARMv8.2-A FP16 scalar instructions

This was originally committed as r255762, but reverted as it broke windows
bots. Re-commitiing the exact same patch, as the underlying cause was fixed by
r258677.

ARMv8.2-A adds 16-bit floating point versions of all existing VFP
floating-point instructions. This is an optional extension, so all of
these instructions require the FeatureFullFP16 subtarget feature.

The assembly for these instructions uses S registers (AArch32 does not
have H registers), but the instructions have ".f16" type specifiers
rather than ".f32" or ".f64". The top 16 bits of each source register
are ignored, and the top 16 bits of the destination register are set to
zero.

These instructions are mostly the same as the 32- and 64-bit versions,
but they use coprocessor 9 rather than 10 and 11.

Two new instructions, VMOVX and VINS, have been added to allow packing
and extracting two 16-bit floats stored in the top and bottom halves of
an S register.

New fixup kinds have been added for the PC-relative load and store
instructions, but no ELF relocations have been added as they have a
range of 512 bytes.

such that x < y < z < x, meaning that a list of them cannot be correctly
sorted, and the sort order could differ with different standard libraries.

The original implementation sorted classes by ValueName if they were otherwise
equal. This isn't strictly necessary, but some backends seem to accidentally
rely on it. If I reverse this comparison I get 8 test failures spread across
the AArch64, Mips and X86 backends, so I have left it in until those backends
can be fixed.

There was one case in the X86 backend where the observable behaviour of the
