  Some implementation share internal table, which can be optimized
to avoid duplicate data.  The are small code or no changes for x86_64
and powerpc64le, which do not affect performance; but on aarch64 with
gcc-14 I see a slight better code generation due the usage of ldq for
floating point constant loading.

Adhemerval Zanella (3):
  math: Consolidate acosf and asinf internal tables
  math: Consolidate acoshf and asinhf internal tables
  math: Consolidate coshf and sinhf internal tables
