Change fetch_add() to store(1 + load())

As there is only one concurrent writer to the Info struct, we can avoid using
the more expensive fetch_add() function.

Fix -Wsign-compare issues.

These lines could theoretically have overflowed in cases of very large stack
traces etc. Very unlikely, but this was causing warnings when built with
-Wsign-compare, which we intend to enable with Chromium.

In none of these three cases is it trivial to switch to a range-based for loop.
