Details:
- Changed name of set0 and set0_mxn macros to set0s and set0s_mxn,
respectively.
- Added code to the following operations that sets the output operand to
zero if the corresponding scalar is zero (rather than performing the
floating-point multiply, or in the case of setv, copying the value).
This will prevent nan's and inf's from creeping into results from
uninitialized memory.
