05e91e7fe2 perf arm-spe: Add support for ARMv8.3-SPE 
This patch is to support Armv8.3 extension for SPE, it adds alignment
field in the Events packet and it supports the Scalable Vector Extension
(SVE) for Operation packet and Events packet with two additions:

  - The vector length for SVE operations in the Operation Type packet;
  - The incomplete predicate and empty predicate fields in the Events
    packet.

11695142e2 perf arm-spe: Refactor packet header parsing 
The packet header parsing uses the hard coded values and it uses nested
if-else statements.

To improve the readability, this patch refactors the macros for packet
header format so it removes the hard coded values.  Furthermore, based
on the new mask macros it reduces the nested if-else statements and
changes to use the flat conditions checking, this is directive and can
easily map to the descriptions in ARMv8-a architecture reference manual
(ARM DDI 0487E.a), chapter 'D10.1.5 Statistical Profiling Extension
protocol packet headers'.

a54ca19498 perf arm-spe: Support synthetic events 
After the commit ffd3d18c20 ("perf tools: Add ARM Statistical
Profiling Extensions (SPE) support") has been merged, it supports to
output raw data with option "--dump-raw-trace".  However, it misses for
support synthetic events so cannot output any statistical info.

This patch is to improve the "perf report" support for ARM SPE for four
types synthetic events:

  First level cache synthetic events, including L1 data cache accessing
  and missing events;
  Last level cache synthetic events, including last level cache
  accessing and missing events;
  TLB synthetic events, including TLB accessing and missing events;
  Remote access events, which is used to account load/store operations
  caused to another socket.

Example usage:

  $ perf record -c 1024 -e arm_spe_0/branch_filter=1,ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ dd if=/dev/zero of=/dev/null count=10000
  $ perf report --stdio
