[AArch64][Patch 3/5] Adjust maximum number of instruction aliases. 

The Statistical Profile Extension adds the instruction PSB CSYNC as an
alias for the HINT #17 instruction. The HINT instruction currently has 8
aliases, which is the maximum number allowed. This patch raises to 16
the limit on the number of aliases an instruction can have.
