Adhemerval Zanella 81a1443941 wcsmbs: optimize wcscat 
This patch rewrites wcscat using wcslen and wcscpy.  This is similar to
the optimization done on strcat by 6e46de42fe.

The strcpy changes are mainly to add the internal alias to avoid PLT
calls.

Checked on x86_64-linux-gnu and a build against the affected
architectures.

	* include/wchar.h (__wcscpy): New prototype.
	* sysdeps/powerpc/powerpc32/power4/multiarch/wcscpy-ppc32.c
	(__wcscpy): Route internal symbol to generic implementation.
	* sysdeps/powerpc/powerpc32/power4/multiarch/wcscpy.c (wcscpy):
	Add internal __wcscpy alias.
	* sysdeps/powerpc/powerpc64/multiarch/wcscpy.c (wcscpy): Likewise.
	* sysdeps/s390/wcscpy.c (wcscpy): Likewise.
	* sysdeps/x86_64/multiarch/wcscpy.c (wcscpy): Likewise.
	* wcsmbs/wcscpy.c (wcscpy): Add
	* sysdeps/x86_64/multiarch/wcscpy-c.c (WCSCPY): Adjust macro to
	use generic implementation.
	* wcsmbs/wcscat.c (wcscat): Rewrite using wcslen and wcscpy.
