[patch tree-optimize]: Factor out lable truth_andor as function

[Kai Tietz]

Hello,

This patch factors out the label truth_andor in fold_binary_loc into a
separate function.

2011-07-08  Kai Tietz  <kti...@redhat.com>

        * fold-const.c (fold_truth_andor): Factored out truth_andor
        label from fold_binary as function.
        (fold_binary_loc): Replace truth_andor lable
        by function fold_truth_andor.

Tested for x86_64-pc-linux-gnu. As pre-approved by Richi, applied to
trunk at revision 176043.

Regards,
Kai
