[CodeView] Reserve TypeDatabase records up front.
Most of the time we know exactly how many type records we
have in a list, and we want to use the visitor to deserialize
them into actual records in a database. Previously we were
just using push_back() every time without reserving the space
up front in the vector. This is obviously terrible from a
performance standpoint, and it's not uncommon to have PDB
files with half a million type records, where the performance
degredation was quite noticeable.
