target-arm: A64: Implement PMULL instruction
Implement the PMULL instruction; this is the last unimplemented insn
in the three-reg-diff group.
Note that PMULL with size 3 is considered part of the AES part
of the crypto extensions (see the ID_AA64ISAR0_EL1 register definition
in the v8 ARM ARM), so it isn't necessary to burn an extra feature
bit on it, even though we're using more feature bits than a single
"crypto extension present/not present" toggle.
