When processing the literal constants of the various kinds of INTEGER that are too large by 1 (e.g., 2147483648_4) in expression analysis, emit a portability warning rather than a fatal error if the literal constant appears as the operand to a unary minus, since the folded result will be in range. And don't emit any warning if the negated literal is coming from a module file -- f18 wrote the module file and the warning would simply be confusing, especially to the programmer that wrote (-2147483647_4-1) in the first place. Further, emit portability warnings for the canonical expressions for infinities and NaN (-1./0., 0./0., & 1./0.), but not when they appear in a module file, for the same reason. The Fortran language has no syntax for these special values so we have to emit expressions that fold to them.
