give up insn attr handles_frame

Browse source 
I introduced this mechanism in r62051 to speed things up. Later it
was reported that the change causes problems.  I searched for
workarounds but nothing seemed appropriate.  I hereby officially
give it up.  The idea to move ADD_PC around was a mistake.

Fixes [Bug #14809] and [Bug #14834].
