Johan B.W. de Vries 46b06dbcf1 Cleanup: TYPE_INFO_MAP
This also removes the InternalPassAsPointer experiment.

This also fixes that u8 values were stores as 32 bits
in structs and tuples (but not dynamic arrays since that
is special cased as bytes).

Also, fixes allocation issue wi	th dynamic arrays, it
would allocate quadratic amount of memory.
