[PATCH v3 07/18] perf python: Expose sample instruction length

[James Clark]

Expose perf_sample::insn_len as a read-only insn_len attribute.

Trace decoders supply instruction lengths on synthesized samples to
indicate whether an instruction was executed or not during a call or
exception. Let scripts read this value directly.
