[PATCH] Fix placement of break stmt in genmatch generated files

[Richard Biener]

This fixes an error I introduced by

2014-11-09  Richard Biener  <rguent...@suse.de>

        * match.pd: Add patterns convering two conversions in a row
        from fold-const.c.
        * fold-const.c (fold_unary_loc): Remove them here.
        * tree-ssa-forwprop.c (combine_conversions): Likewise.
        * genmatch.c (dt_node::gen_kids): Check whether we may
        follow SSA use-def chains.

where I avoided an extra {} nesting but failed to move the break
stmt out of the conditional block.  This results in unwanted fallthrus
(non-fatal for the patterns currently in trunk match.pd).

Bootstrapped & tested on x86_64-unknown-linux-gnu, applied.

Richard.
