Masami Hiramatsu (Google) 738b78ee4b tracing/probes: Add $current variable support
Since we can use the BTF to cast value to a structure pointer type,
it is useful to introduce "$current" special variable support to
fetcharg.

User can define a fetcharg to access current task_struct properties
using BTF info. e.g.

  $current->cpus_ptr
