It is generally more useful to show the symbol with an address. In this
case, the print function requires the 'machine' which means changing
callers to provide it as a parameter. It is optional because most events
do not need it and the callers that matter can provide it.

In the absence of any modules, no "modules" map is created, but there are
other executable pages to map, due to eBPF JIT, kprobe or ftrace. Map them
by recognizing that the first "module" symbol is not necessarily from a
module, and adjust the map accordingly.

Consistent with other new events, add an option to perf script to display
text poke events and ksymbol events. Both text poke events and ksymbol
events are displayed because some text pokes (e.g. ftrace trampolines) have
corresponding ksymbol events.

Events marked as 'immediate' are started before other events to ensure
that there is context at the start of the main tracing events. The same
is true at the end of tracing, so disable 'immediate' events after other

Symbols are needed for tools to describe instruction addresses. Pages
allocated for ftrace's purposes need symbols to be created for them.
Add such symbols to be visible via perf ksymbol events.
