15bfc148c7 roots.hpp: correct flaw in previous commit. 
If the next step jumps out of bounds, we need to fix up the sign of
the result, otherwise the bounds get incorrectly updated.

70162dbcb8 Update second order root finding code to bracket root when required. 
When min and max differ by many orders of magnitude (as happens when one is
zero for example), then bisection can take a very long time to iterate down to
the root.  Instead use a bracketing strategy which doubles the step size with
each iteration until a bracket is found, then repeat recursively as required
until we have a reasonably small interval.  Note that this only kicks in when
a Halley step goes out of bounds and we're therefore forced to thrash around
looking for the root.  Fixes: https://github.com/boostorg/math/issues/204.

c759981a2a Improve performance of sin_pi and cos_pi: 
Use a static_cast to int when available for parity checking as it's much faster than itrunc.
Don't check for overflows in the result, since we know the result is in [-1,1].
