JJenkxandClaude Opus 5.5 e601dbd7a4 fix(libc): compute sinf, cosf, tanf and sincosf with FreeBSD msun's algorithms, as titles' libc.prx does ...

They returned the host sin, cos and tan, so their last bit and errno
depended on the host: on Windows sinf differs from the libc.prx that titles
ship on 3,349,410 of the 2^32 floats, cosf on 3,382,210 and tanf on
303,874,018. That libc.prx is msun's s_sinf.c, s_cosf.c and s_tanf.c over
the double-precision kernels and e_rem_pio2f.c with k_rem_pio2.c; its
sincosf returns the same pair, and only an infinite argument sets EDOM.
The ports give the same bits and errno as PPSA07923's, PPSA05916's and
PPSA13934's copies for every argument.
