a35a59036e x86_64: Use %xmmN with vpxor to clear a vector register
Since "vpxor %xmmN, %xmmN, %xmmN" clears the whole vector register, use
%xmmN, instead of %ymmN, with vpxor to clear a vector register.

5a82c74822 Prefer https to http for gnu.org and fsf.org URLs
Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:

sed -ri '
  s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
  s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g
' \
  $(find $(git ls-files) -prune -type f \
      ! -name '*.po' \
      ! -name 'ChangeLog*' \
      ! -path COPYING ! -path COPYING.LIB \
      ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \
      ! -path manual/texinfo.tex ! -path scripts/config.guess \
      ! -path scripts/config.sub ! -path scripts/install-sh \
      ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \
      ! -path INSTALL ! -path  locale/programs/charmap-kw.h \
      ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \
      ! '(' -name configure \
            -execdir test -f configure.ac -o -f configure.in ';' ')' \
      ! '(' -name preconfigure \
            -execdir test -f preconfigure.ac ';' ')' \
      -print)

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:

  chmod a+x sysdeps/unix/sysv/linux/riscv/configure
  # Omit irrelevant whitespace and comment-only changes,
  # perhaps from a slightly-different Autoconf version.
  git checkout -f \
    sysdeps/csky/configure \
    sysdeps/hppa/configure \
    sysdeps/riscv/configure \
    sysdeps/unix/sysv/linux/csky/configure
  # Omit changes that caused a pre-commit check to fail like this:
  # remote: *** error: sysdeps/powerpc/powerpc64/ppc-mcount.S: trailing lines
  git checkout -f \
    sysdeps/powerpc/powerpc64/ppc-mcount.S \
    sysdeps/unix/sysv/linux/s390/s390-64/syscall.S
  # Omit change that caused a pre-commit check to fail like this:
  # remote: *** error: sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S: last line does not end in newline
  git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

d2538b9156 x86-64: Optimize strrchr/wcsrchr with AVX2
Optimize strrchr/wcsrchr with AVX2 to check 32 bytes with vector
instructions.  It is as fast as SSE2 version for small data sizes
and up to 1X faster for large data sizes on Haswell.  Select AVX2
version on AVX2 machines where vzeroupper is preferred and AVX
unaligned load is fast.

	* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
	strrchr-sse2, strrchr-avx2, wcsrchr-sse2 and wcsrchr-avx2.
	* sysdeps/x86_64/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Add tests for __strrchr_avx2,
	__strrchr_sse2, __wcsrchr_avx2 and __wcsrchr_sse2.
	* sysdeps/x86_64/multiarch/strrchr-avx2.S: New file.
	* sysdeps/x86_64/multiarch/strrchr-sse2.S: Likewise.
	* sysdeps/x86_64/multiarch/strrchr.c: Likewise.
	* sysdeps/x86_64/multiarch/wcsrchr-avx2.S: Likewise.
	* sysdeps/x86_64/multiarch/wcsrchr-sse2.S: Likewise.
	* sysdeps/x86_64/multiarch/wcsrchr.c: Likewise.
