Use libm_alias_double for more dbl-64 functions.

This patch makes more dbl-64 functions use libm_alias_double to define
function aliases.  Specifically, it makes the change for functions
with dbl-64/wordsize-64 versions, changing both the dbl-64 and
dbl-64/wordsize-64 versions and removing the ldbl-opt wrappers.
Functions are excluded from this patch if there are complications
because of versions of those functions also present in libc, or
architecture-specific wrappers round these files.

Tested for x86_64, and with build-many-glibcs.py.  Installed stripped
shared libraries are unchanged except for alpha (where increased use
of dbl-64/wordsize-64 files, where previously ldbl-opt files that
wrapped dbl-64 files were used, was expected to result in different,
better code).
