octave: liboctave/numeric/lo-mappers.h annotate

annotate liboctave/numeric/lo-mappers.h @ 23665:90fdfe448ae6

Promote simple functions from lo-mappers.cc to inline versions in lo-mappers.h Benchmark shows 4% performance improvement. * lo-mappers.cc (exp2, copysign, signbit, trunc, floor, round, isnan, isfinite, isinf): Delete functions. * lo-mappers.h (exp2, copysign, signbit, trunc, floor, round, isnan, isfinite, isinf): new inline functions that forward to std library.
