Remove slow paths from exp
Remove the __slowexp code, so exp is no longer correctly rounded. The
result is computed to about 70 bits precision so the worst case ulp
error is about 0.500007 in nearest rounding mode.
* manual/probes.texi: Remove slowexp probes.
* math/Makefile: Remove slowexp.
* sysdeps/generic/math_private.h (__slowexp): Remove.
* sysdeps/ieee754/dbl-64/e_exp.c (__ieee754_exp): Remove __slowexp and
document error bounds.
* sysdeps/i386/fpu/slowexp.c: Remove.
* sysdeps/ia64/fpu/slowexp.c: Remove.
* sysdeps/ieee754/dbl-64/slowexp.c: Remove.
* sysdeps/ieee754/dbl-64/uexp.h (err_0): Remove.
* sysdeps/m68k/m680x0/fpu/slowexp.c: Remove.
* sysdeps/powerpc/power4/fpu/Makefile (CPPFLAGS-slowexp.c): Remove.
* sysdeps/x86_64/fpu/multiarch/Makefile: Remove slowexp-fma.
* sysdeps/x86_64/fpu/multiarch/e_exp-avx.c (__slowexp): Remove.
* sysdeps/x86_64/fpu/multiarch/e_exp-fma.c (__slowexp): Remove.
* sysdeps/x86_64/fpu/multiarch/e_exp-fma4.c (__slowexp): Remove.
* sysdeps/x86_64/fpu/multiarch/slowexp-avx.c: Remove.
* sysdeps/x86_64/fpu/multiarch/slowexp-fma.c: Remove.
* sysdeps/x86_64/fpu/multiarch/slowexp-fma4.c: Remove.
