[ARM] ARM mov InstAlias for MOVW lacks HasV6T2
The movw instruction is only available in ARM state for V6T2 and above.
The MOVi16 instruction has requirement HasV6T2 but the InstAlias
for mov rd, imm where the operand is imm0_65535_expr:$imm does not.
This means that movw can incorrectly be used in ARMv4 and ARMv5 by
writing mov rd, 0x1234. The simple fix is to the requirement HasV6T2
to the InstAlias. Tests added to not-armv4.s.
Patch by Peter Smith.
