Some of the MAS register macros do not protect the parameter with parentheses, which could cause wrong values if the parameter includes operators.
Also fix the definition of TSIZE_TO_BYTES() so that it actually uses the parameter. This hasn't caused any problems to date because the parameter was always been 'tsize'.
