Gabriel F. T. Gomes e18a305777 Refactor *cvt functions implementation (1/2)
This patch refactors the *cvt functions implementation in a way that
makes it easier to re-use them for implementing the IEEE long double on
powerpc64le.  By splitting the implementation per se in one file
(efgcvt-template.c) and the alias definitions in others (e.g. efgcvt.c),
the new code makes it easier to define new function names, such as
__qecvtieee128.

Tested that installed stripped binaries for all build-many-glibcs
targets remain identical before and after this patch.  Also tested for
powerpc64le and x86_64.
