The type suffix for a conversion operator denotes the type of the result and the size indicator gives the size of the result.

For example, if syms[0] in a CVUI4 points to a symbol-table entry for 2, the conversion widens a 2-byte unsigned integer to a 4-byte signed integer. Conversions that widen unsigned integers zero-extend; those that widen signed integers sign-extend.
