Change powerpc64le's long double from 64-bit double to IEEE 754 binary128 (quad, 113-bit mantissa), matching aarch64 and riscv64. Gated on FreeBSD 16 and powerpc64le only. Differential Revision: https://reviews.freebsd.org/D57388 Reviewed by: adrian Relnotes: yes

// PowerPC names the IEEE binary128 comparison soft-float routines with a "kf"

|
// infix instead of the generic "tf". The semantics are identical to the

|
// generic comparetf2.c routines; only the exported names differ. We provide

// __lekf2(a,b) returns -1 if a < b, 0 if a == b, 1 if a > b, 1 if NaN
|
|
// __gekf2(a,b) returns -1 if a < b, 0 if a == b, 1 if a > b, -1 if NaN
|

// __unordkf2(a,b) returns 1 if either operand is NaN, 0 otherwise
