LibF7: Use monic denominator polynomials to save a multiplication.
libgcc/config/avr/libf7/
* libf7.h (F7_FLAGNO_plusx, F7_FLAG_plusx): New macros.
* libf7.c (f7_horner): Handle F7_FLAG_plusx in highest coefficient.
* libf7-const.def [F7MOD_atan_]: Denominator: Set F7_FLAG_plusx
and omit highest term.
[F7MOD_asinacos_]: Use rational function with normalized denominator.
