math: lgamma cleanup (simpler sin(pi*x) for the negative case)
* simplify sin_pi(x) (don't care about inexact here, the result is
inexact anyway, and x is not so small to underflow)
* in lgammal add the previously removed special case for x==1 and
x==2 (to fix the sign of zero in downward rounding mode)
* only define lgammal on supported long double platforms
* change tgamma so the generated code is a bit smaller
