Remove the error handling wrapper from exp and exp2
Introduce new exp and exp2 symbol version that don't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The double precision wrappers are disabled for sysdeps/ieee754/dbl-64 by using empty w_exp.c and w_exp2.c files, the math/w_exp.c and math/w_exp2.c files use the wrapper template and can be included by targets that have their own exp and exp2 implementations or use ifunc on the glibc internal __ieee754_exp symbol. The compatibility symbol versions still use the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously expl and exp2l were aliases of exp and exp2, now they point to the compatibility symbols with the wrapper, because they still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The _finite symbols are now aliases of the standard symbols (they have no performance advantage anymore). Both the standard symbols and _finite symbols set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include <math.h> was added before macro definitions that may affect that header (the new macro name is __exp instead of __ieee754_exp which breaks some math.h macros). Tested with build-many-glibcs.py. * math/Versions (GLIBC_2.29): Add exp and exp2. * math/w_exp2_compat.c (__exp2_compat): Change to versioned compat symbol, handle NO_LONG_DOUBLE and LONG_DOUBLE_COMPAT explicitly. * math/w_exp_compat.c (__exp_compat): Likewise. * math/w_exp.c: New file. * math/w_exp2.c: New file. * sysdeps/i386/fpu/w_exp.c: New file. * sysdeps/i386/fpu/w_exp2.c: New file. * sysdeps/ia64/fpu/e_exp.S: Add versioned symbols. * sysdeps/ia64/fpu/e_exp2.S: Likewise. * sysdeps/ieee754/dbl-64/e_exp.c (__ieee754_exp): Rename to __exp and add necessary aliases. * sysdeps/ieee754/dbl-64/e_exp2.c (__ieee754_exp2): Rename to __exp2 and add necessary aliases. * sysdeps/ieee754/dbl-64/w_exp.c: New file. * sysdeps/ieee754/dbl-64/w_exp2.c: New file. * sysdeps/m68k/m680x0/fpu/w_exp.c: New file. * sysdeps/m68k/m680x0/fpu/w_exp2.c: New file. * sysdeps/mach/hurd/i386/libm.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/libm.abilist: Update. * sysdeps/unix/sysv/linux/alpha/libm.abilist: Update. * sysdeps/unix/sysv/linux/arm/libm.abilist: Update. * sysdeps/unix/sysv/linux/hppa/libm.abilist: Update. * sysdeps/unix/sysv/linux/i386/libm.abilist: Update. * sysdeps/unix/sysv/linux/ia64/libm.abilist: Update. * sysdeps/unix/sysv/linux/m68k/coldfire/libm.abilist: Update. * sysdeps/unix/sysv/linux/m68k/m680x0/libm.abilist: Update. * sysdeps/unix/sysv/linux/microblaze/libm.abilist: Update. * sysdeps/unix/sysv/linux/mips/mips32/libm.abilist: Update. * sysdeps/unix/sysv/linux/mips/mips64/libm.abilist: Update. * sysdeps/unix/sysv/linux/nios2/libm.abilist: Update. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libm.abilist: Update. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libm.abilist: Update. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Update. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm.abilist: Update. * sysdeps/unix/sysv/linux/s390/s390-32/libm.abilist: Update. * sysdeps/unix/sysv/linux/s390/s390-64/libm.abilist: Update. * sysdeps/unix/sysv/linux/sh/libm.abilist: Update. * sysdeps/unix/sysv/linux/sparc/sparc32/libm.abilist: Update. * sysdeps/unix/sysv/linux/sparc/sparc64/libm.abilist: Update. * sysdeps/unix/sysv/linux/x86_64/64/libm.abilist: Update. * sysdeps/unix/sysv/linux/x86_64/x32/libm.abilist: Update. * sysdeps/x86_64/fpu/multiarch/e_exp-avx.c (__exp1): Remove.
