The ARMv8.3-SPE adds an Alignment Flag in the Events packet and filtering
on this event using PMSEVFR_EL1, together with support for the profiling
of Scalable Vector Extension operations.

Patch 1: Update the kernel driver, mainly for PMSEVFR_EL1.

Patch 2: Update the decode process of Events packet and Operation Type
  packet in perf tool.

Patch 3-4: Synthesize unaligned address access events and partial/empty
  predicated SVE events, also add two itrace options for filtering.
