Improve unit testing of for-loops.

An ES2-compatible for loop supports six separate rel-ops:
   < <= > >= != ==
Each rel-op, in addition to its expected usage, is also able to
represent a loop which never terminates, as well as a loop which
terminates instantly. Since SkVM unrolls these loops, we should make
sure we do it properly. We now have unit tests for all of these cases.
