Perhaps B::Concise helps? 

# in code.pl, for example
if ( /test1/ ) { print; }
my $re = qr/test2/;
my @array = split( /test3/, $ARGV[0] );

[download]

perl -MO=Concise,-exec code.pl | grep "</>"

produces the output, 

code.pl syntax OK
3  </> match(/"test1"/) s/RTIME
9  </> qr(/"test2"/) s/64
e  </> pushre(/"test3"/) s/64

"</>" is the symbol for an OP with a regular expression. Someone smarter than I might tell you whether this will catch all the regex cases. If the regex is read in at runtime (with YAML or Storable, for example) I think B::Concise would tell you there was a regex involved, but not what it was.
