Subject: [PATCH v5 09/21] perf script: Move script_fetch_insn to trace-event-scripting.c
Add native_arch as a parameter to script_fetch_insn rather than
relying on the builtin-script value that won't be initialized for the
dlfilter and python Context use cases. Assume both of those cases are
running natively.
