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.
