This area of history is particularly hairy because of all the back-and-forth
merging between //depot/perl and //depot/cfgperl, which confuses bisect.
It's also potentially interesting, as it's the start of the 5.6.0 development
series, so many new features arrive in quick succession, making it a likely
spot for regressions to appear.

In particular, we can now build perl for this commit:
