math: new software sqrtl
same approach as in sqrt. sqrtl was broken on aarch64, riscv64 and s390x targets because of missing quad precision support and on m68k-sf because of missing ld80 sqrtl. this implementation is written for quad precision and then edited to make it work for both m68k and x86 style ld80 formats too, but it is not expected to be optimal for them. note: using fp instructions for the initial estimate when such instructions are available (e.g. double prec sqrt or rsqrt) is avoided because of fenv correctness.
