d1311ac171 [ARM] Introduce the 'sevl' instruction in ARMv8.
This also removes the restriction on the immediate field of the 'hint'
instruction.

1ad3a410be ARM: Fix encoding of hint instruction for Thumb.
"hint" space for Thumb actually overlaps the encoding space of the CPS
instruction. In actuality, hints can be defined as CPS instructions where imod
and M bits are all nil.

Handle decoding of permitted nop-compatible hints (i.e. nop, yield, wfi, wfe,
sev) in DecodeT2CPSInstruction.

This commit adds a proper diagnostic message for Imm0_4 and updates all tests.

Patch by Mihail Popa <Mihail.Popa@arm.com>.
