Merge #13241: scripted-diff: Avoid temporary copies when looping over std::map
9b72c988a0 scripted-diff: Avoid temporary copies when looping over std::map (Ben Woosley)
Pull request description:
The ::value_type of the std::map/std::multimap/std::unordered_map containers is
std::pair<const Key, T>. Dropping the const results in an unnecessary copy,
for example in C++11 range-based loops.
For this I started with a more general scripted diff, then narrowed it down
based on the inspection showing that all actual map/multimap/unordered_map
variables used in loops start with m or have map in the name.
