perf symbols: Don't demangle parameters and such by default
Some C++ symbols have very long name and they make column length longer.
Most of them are about parameters including templates and we can ignore
such info most of time IMHO.
This patch passes DMGL_NO_OPTS by default when calling bfd_demangle().
One can still see full symbols with -v/--verbose option.
before:
JS_CallFunctionValue(JSContext*, JSObject*, JS::Value, unsigned int, JS::Value*, JS::Value*)
after:
JS_CallFunctionValue
