[PATCH 4/8] perf arm-spe: Fill address info for samples

[James Clark]

From: Leo Yan <leo.yan@xxxxxxxxxx>

To properly handle memory and branch samples, this patch divides into
two functions for generating samples: arm_spe__synth_mem_sample() is for
synthesizing memory and TLB samples; arm_spe__synth_branch_sample() is
to synthesize branch samples.

Arm SPE backend decoder has passed virtual and physical address through
packets, the address info is stored into the synthesize samples in the
function arm_spe__synth_mem_sample().
