[Bug translator/9930] New: produce more information about probe reentrancy

["fche at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

With tracepoints, it's easy to generate unintentionally reentrant probes.

# stap -t -e 'probe trace("*") {}' -w

running for a while produces 

WARNING: Number of errors:, skipped probes: NNN
WARNING: Skipped due to reentrancy: NNN

It would be nice to track which probes are reentrant with respect to which
others.  The results may be very intuitive (tracepoints associated with
hardware interrupts), in which case we may need to relax the MAXSKIPPED/etc.
logic for reentrancy, so that such a common case is not penalized.
