Bump __FreeBSD_version for the addition of cacoshl, cacosl, casinhl, casinl, catanl, catanhl, sincos, sincosf, and sincosl. MFC r305382 (by bde): Add asm versions of fmod(), fmodf() and fmodl() on amd64. Add asm versions of fmodf() amd fmodl() on i387. fmod is similar to remainder, and the C versions are 3 to 9 times slower than the asm versions on x86 for both, but we had the strange mixture of all 6 variants of remainder in asm and only 1 of 6 variants of fmod in asm. MFC r305384 (by bde): Disconnect the "optimized" asm variants of cos(), sin() and tan() from the build on i386. Leave them in the source tree for regression tests. The asm functions were always much less accurate (by a factor of more than 10**18 in the worst case). They were faster on old CPUs. But with each new generation of CPUs they get relatively slower. The double precision C version's average advantage is about a factor of 2 on Haswell. The asm functions were already intentionally avoided in float and long double precision on i386 and in all precisions on amd64. Float precision and amd64 give larger advantages to the C version. The long double precision C code and compilers' understanding of long double precision are not so good, so the i387 is still slightly faster for long double precision, except for the unimportant subcase of huge args where the sub-optimal C code now somehow beats the i387 by about a factor of 2. MFC r305385 (by bde): Oops, the previous i386 version of e_fmodf.S and e_fmodl.S was actually the amd64 version.
