perf report: Adjust sample type validation for synthesized branch stacks
perf report looks at event sample types to determine if branch stacks
have been sampled. Adjust the validation to know about instruction
tracing options.
This change allows the use of the -b option which otherwise would
complain with an error like:
Error:
Selected -b but no branch data. Did you call perf record without -b?
# To display the perf.data header info,
# please use --header/--header-only options.
