Improve maintainability of complex loops.

1. Avoid looping over two expressions in parallel when one makes more
   sense (compilers can do strength reduction optimization: we don't
   need to do it ourselves).

2. Introduce macro ITER_PARALLEL for iterating over two expressions in
   parallel, to clarify the intention and explain the need for the
   cast to void in the implementation.

3. Add macros SAC_LARGE_ITER and SAC_SMALL_ITER to reduce the amount
   of code duplication in sac.c.

Ensure that the mps builds with "clang -werror -wcomma -std=c89".

The -Wcomma option appears to be turned on automatically by Xcode
12.3, so it's a good idea for the MPS to build with the option, to
avoid unpleasant surprises when people update their Xcode.

The simplest way to suppress the warning is to cast the left hand side
of the comma operator to void.
