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().

Committer notes:

Fixed this:
