This patch adds an ifunc variant to use the cu instruction on arch12 CPUs.
This new ifunc variant can be built if binutils support z13 vector
instructions. At runtime, HWCAP_S390_VXE decides if we can use the
cu24 instruction.
ChangeLog:
* sysdeps/s390/utf16-utf32-z9.c (__from_utf16_loop_vx_cu):
Use vector and cu24 instruction.
* sysdeps/s390/multiarch/utf16-utf32-z9.c:
Add __from_utf16_loop_vx_cu in ifunc resolver.

macro.
The utf16-utf32-z9.c iconv module is using ifunc and thus the ifunc part should
be in multiarch folder. Otherwise ifunc is used even if you configure
with --disable-multi-arch.
This patch moves the ifunc resolvers to the new file
sysdeps/s390/multiarch/utf16-utf32-z9.c. The resolvers are now implemented
with s390_libc_ifunc_expr macro instead of using gcc attribute ifunc directly.
The ifunc versions are implemented in sysdeps/s390/utf16-utf32-z9.c.
Each version is only implemented if needed or supported. Therefore there is
a block at beginning of the file which selects the versions which should be
defined depending on support for multiarch, vector-support and used minimum
architecture level. This block defines HAVE_[FROM|TO]_[C|VX] to 1 or 0.
The code below is rearranged and surrounded
by #if HAVE_[FROM|TO]_[C|VX] == 1. There is no functional change.
ChangeLog:
* sysdeps/s390/multiarch/utf16-utf32-z9.c: New File.
* sysdeps/s390/utf16-utf32-z9.c: Move ifunc resolvers to multiarch
folder and define ifunc versions depending on HAVE_[FROM|TO]_[C|VX].
(HAVE_FROM_C, HAVE_FROM_VX, HAVE_TO_C, HAVE_TO_VX, FROM_LOOP_DEFAULT,
FROM_LOOP_C, FROM_LOOP_VX, TO_LOOP_DEFAULT, TO_LOOP_C, TO_LOOP_VX):
New Define.
