Break more lines before not after operators.

This patch makes further coding style fixes where code was breaking
lines after an operator, contrary to the GNU Coding Standards.  As
with the previous patch, it is limited to files following a reasonable
approximation to GNU style already, and is not exhaustive; more such
issues remain to be fixed.

Tested for x86_64, and with build-many-glibcs.py.
