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. Reviewed-by: Paul E. Murphy <murphyp@linux.ibm.com>
