[PATCH] [PR86710][PR116826] match.pd: Fold logarithmic identities.

This patch implements 4 rules for logarithmic identities in match.pd under -funsafe-math-optimizations: 1) logN(1.0/a) -> -logN(a). This avoids the division instruction. 2) logN(C/a) -> logN(C) - logN(a), where C is a real constant. Same as 1). 3) logN(a) + logN(b) -> logN(a*b). This reduces the nu
