without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the ninth batch of tests being updated (there are a
significant number of other tests left to be updated).
Summary:
New logic tries to narrow possible result values of the remainder operation
based on its operands and their ranges. It also tries to be conservative
with negative operands because according to the standard the sign of
the result is implementation-defined.

When neither LHS nor RHS of a binary operator expression can be simplified,
return the original expression instead of re-evaluating the binary operator.
Such re-evaluation was causing recusrive re-simplification which caused
the algorithmic complexity to explode.
