tree-ssa-structalias / pta: Fix *more* GNU coding style deviations

This continues my previous commit, where I fixed some deviations from
GNU coding style in pta files.  This should fix all the remaining issues
that contrib/check_GNU_style.py can detect (excluding false positives).

Commiting as obvious.
