This fixes a non-determinism issue caused by the cache being full.
Depending on the non-deterministic value of the handles in HeapConstant
nodes, different cache entries would be overwritten in this case.
The old implementation of NodeCache had a fixed limit, overwriting
entries when the cache is full. This behavior didn't really make sense,
but the hand-written hash map implementation couldn't handle arbitrary
numbers of hash collisions, so removing the limit wasn't an option either.
Thus this CL just replaces the custom hash map with a normal
std::unordered_map, that is, a ZoneUnorderedMap.

This replaces all typedefs that define types and not functions by the
equivalent "using" declaration.
This was done mostly automatically using this command:
ag -l '\btypedef\b' src test | xargs -L1 \
perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg'
Patchset 2 then adds some manual changes for typedefs for pointer types,
where the regular expression did not match.
