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'.
