bug#8377: 23.2; compile regexp for perl Test.pm "fail #N"

[Kevin Ryde]

For the compile.el error regexps, perl's Test.pm can add a "fail #N" if
a given test line is run more than once, in a loop or subr.  The
`perl--Test2' could match that per below.  (Still no good on bzr, so
individual diffs.)

        * progmodes/compile.el (compilation-error-regexp-alist-alist):
        `perl-Test2' extend to match possible "fail #N" rep count.

        * compilation.txt (perl-Test2): New samples.
