This change is to implement following rules:

  o. X/C1 * C2 => X * (C2/C1) (if C2/C1 is neither special FP nor denormal)
  o. X/C1 * C2 -> X/(C1/C2)   (if C2/C1 is either specical FP or denormal, but C1/C2 is a normal Fp)

     Let MDC denote multiplication or dividion with one & only one operand being a constant
  o. (MDC ± C1) * C2 => (MDC * C2) ± (C1 * C2)
     (so long as the constant-folding doesn't yield any denormal or special value)

This is necessary not only for representing empty ranges, but for handling
multibyte characters in the input. (If the end pointer in a range refers to
a multibyte character, should it point to the beginning or the end of the
character in a char array?) Some of the code in the asm parsers was already

turning a code like this:

if (foo)
   free(foo)

into that:
free(foo)

Move a call to free from basic block FB into FB's predecessor, P,
when the path from P to FB is taken only if the argument of free is
not equal to NULL.

Some restrictions apply on P and FB to be sure that this code motion
is profitable. Namely:
1. FB must have only one predecessor P.
2. FB must contain only the call to free plus an unconditional
   branch to S.
3. P's successors are FB and S.

Because of 1., we will not increase the code size when moving the call
to free from FB to P.
Because of 2., FB will be empty after the move.
Because of 2. and 3., P's branch instruction becomes useless, so as FB
(simplifycfg will do the job).
