Zachary Turner 522178bccc [CodeView Type Merging] Don't keep re-allocating temp serializer. ... Previously, every time we wanted to serialize a field list record, we would create a new copy of FieldListRecordBuilder, which would in turn create a temporary instance of TypeSerializer, which itself had a std::vector<> that was about 128K in size. So this 128K allocation was happening every time. We can re-use the same instance over and over, we just have to clear its internal hash table and seen records list between each run. This saves us from the constant re-allocations. This is worth an ~18.5% speed increase (3.75s -> 3.05s) in my tests.
