These are local containers that are either:
- Already const and didn't need Q_FOREACH to begin with
- Can be simply made const, just by adding const keyword
In one case the unittest checked that the container's size is 1, so use
list.first() instead of a for-loop.
In files where Q_FOREACH isn't used any more, remove
"#undef QT_NO_FOREACH". Also remove those files from NO_PCH_SOURCES.
Drive-by changes:
- Remove parenthesis from one-line for-loops
- Make the for-loop variable a const& where a copy isn't needed
