* fold-const.c (fold binary) <RDIV_EXPR>: Optimize
sin(x)/tan(x) as cos(x) and tan(x)/sin(x) as 1.0/cos(x)
when flag_unsafe_math_optimizations is set and
we don't care about NaNs or Infinities.
Move x/expN(y) and x/pow(y,z) transformation into common
flag_unsafe_math_optimizations section.

* gcc.dg/builtins-20.c: Add checks for sin(x)/tan(x) and
tan(x)/sin(x) transformations.
