Joey Gouly dce01792f2 Add Thumb tests for the ARMv8 FP instructions that I recently added.
Also, fix the namespace for two instructions that I missed previously.

Joey Gouly cc4ff9e907 Add support for MC assembling and disassembling of vsel{ge, gt, eq, vs} instructions.
This adds a new decoder table/namespace 'VFPV8', as these instructions have their
top 4 bits as 0b1111, while other Thumb instructions have 0b1110.

Mihai Popa 1c7be576c5 This patch adds support for FPINST/FPINST2 as operands to vmsr/vmrs. These are optional registers that may be supported some ARM implementations to aid with resolution of floating point exceptions. The manual pages for vmsr and vmrs do not detail their use. Encodings and other information can be found in ARM Architecture Reference Manual section F, chapter 6, paragraph 3.

Tim Northover 4173e29a98 ARM: add fstmx and fldmx instructions for assembly
These instructions are deprecated oddities, but we still need to be able to
disassemble (and reassemble) them if and when they're encountered.

Anton Korobeynikov c6d945b11a The names of VFP variants of half-to-float conversion instructions were
reversed. This leads to wrong codegen for float-to-half conversion
intrinsics which are used to support storage-only fp16 type.
NEON variants of same instructions are fine.

Evan Cheng 48346c1cd9 Clean up ARM fused multiply + add/sub support some more: rename some isel
predicates.
Also remove NEON2 since it's not really useful and it is confusing. If
NEON + VFP4 implies NEON2 but NEON2 doesn't imply NEON + VFP4, what does it
really mean?

Lang Hames 718cfbe05a Split fpscr into two registers: FPSCR and FPSCR_NZCV.
The fpscr register contains both flags (set by FP operations/comparisons) and
control bits. The control bits (FPSCR) should be reserved, since they're always
available and needn't be defined before use. The flag bits (FPSCR_NZCV) should
like to be unreserved so they can be hoisted by MachineCSE. This fixes PR12165.

Sebastian Pop 957a6583f1 updated patch for the ARM fused multiply add/sub
In this update:
- I assumed neon2 does not imply vfpv4, but neon and vfpv4 imply neon2.
- I kept setting .fpu=neon-vfpv4 code attribute because that is what the
assembler understands.
