Also, change sources.redhat.com to sourceware.org.

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.

According to the latest Unicode standard, a conversion from/to UTF-xx has
to report an error if the character value is in range of an utf16 surrogate
(0xd800..0xdfff). See https://sourceware.org/ml/libc-help/2015-12/msg00015.html.
Thus the cu42 instruction, which converts from utf32 to utf16, has to be
disabled because it does not report an error in case of a value in range of
a low surrogate (0xdc00..0xdfff). The etf3eh variant is removed and the c,
vector variant is adjusted to handle the value in range of an utf16 low
surrogate correctly.
ChangeLog:
* sysdeps/s390/utf16-utf32-z9.c: Disable cu42 instruction and report
an error in case of a value in range of an utf16 low surrogate.

This patch reworks the existing s390 64bit specific iconv modules in order
to use them on s390 31bit, too.
Thus the parts for subdirectory iconvdata in sysdeps/s390/s390-64/Makefile
were moved to sysdeps/s390/Makefile so that they apply on 31bit, too.
All those modules are moved from sysdeps/s390/s390-64 directory to sysdeps/s390.
The iso-8859-1 to/from cp037 module was adjusted, to use brct (branch relative
on count) instruction on 31bit s390 instead of brctg, because the brctg is a
zarch instruction and is not available on a 31bit kernel.
The utf modules are using zarch instructions, thus the directive machinemode
zarch_nohighgprs was added to the inline assemblies to omit the high-gprs flag
in the shared libraries. Otherwise they can't be loaded on a 31bit kernel.
The ifunc resolvers were adjusted in order to call the etf3eh or vector variants
only if zarch instructions are available (64bit kernel in 31bit compat-mode).
Furthermore some variable types were changed. E.g. unsigned long long would be
a register pair on s390 31bit, but we want only one single register.
For variables of type size_t the register contents have to be enlarged from a
32bit to a 64bit value on 31bit, because the inline assemblies uses 64bit values
in such cases.
ChangeLog:
* sysdeps/s390/s390-64/Makefile (iconvdata-subdirectory):
Move to ...
* sysdeps/s390/Makefile: ... here.
* sysdeps/s390/s390-64/iso-8859-1_cp037_z900.c: Move to ...
* sysdeps/s390/iso-8859-1_cp037_z900.c: ... here.
(BRANCH_ON_COUNT): New define.
(TR_LOOP): Use BRANCH_ON_COUNT instead of brctg.
* sysdeps/s390/s390-64/utf16-utf32-z9.c: Move to ...
* sysdeps/s390/utf16-utf32-z9.c: ... here and adjust to
run on s390-32, too.
* sysdeps/s390/s390-64/utf8-utf16-z9.c: Move to ...
* sysdeps/s390/utf8-utf16-z9.c: ... here and adjust to
run on s390-32, too.
* sysdeps/s390/s390-64/utf8-utf32-z9.c: Move to ...
