From: "Gabriel F. T. Gomes" <gabrielftg@linux.ibm.com>

Changes since v1:

  - Adapted after patch v1 19/31 (remove hidden_* uses) was dropped.
  - Fixed unintended removal of cvt* symbols on alpha and s390x
    (now tested with build-many-glibcs.py).

-- 8< --
This patch is to be squashed with the other n/5 refactoring patches.

This patch splits the definition of the symbol names into separate files
for double and long double, which will make it easier to define new
symbol names for IEEE long double functions on powerpc64le.
