preproc/symtable: Linear-time type resolution 

This was optimized previously, having introduced
`@need-resolve-dtype`.  But, while that solved the problem for some
packages, it was not enough for a package with 40,000 symbols.

This introduces a map for typedefs' symbols and eliminates ~15s for that
package.
