AArch64: Wire through instr_sequence

This patch introduces aarch64_instr_sequence which is a structure similar to IT
blocks on Arm in order to track instructions that introduce a constraint or
dependency on instruction 1..N positions away from the instruction that opened
the block.

The struct is also wired through to the locations that require it.
