sizeof_i_i opcode uses old integer types.

[coke]

=item B<sizeof>(out INT, in INT)

Get the size of native datatype $2 in $1.

This opcode either needs to be removed or updated to use a named type.

Added a deprecation notice and marked opcode as deprecated in r44286.

If you want this opcode or something like it, should probably mention in before 2.4.

An ability to get information from the system about the sizes of datatypes would definitely be interesting. Since the info is stored in include/parrot/datatypes.h anyway, we could expose it through another interface such as a method on the ParrotInterpreter object.
