This patch consolidates all the pwritev{64} implementation for Linux
in only one (sysdeps/unix/sysv/linux/pwritev{64}.c). It also removes the
syscall from the auto-generation using assembly macros.
It was based on previous pwrite/pwrite64 consolidation patch. The new macro
SYSCALL_LL{64} is used to handle the offset argument and alias is created
for __ASSUME_OFF_DIFF_OFF64 in case of pread64.
Checked on x86_64, i386, aarch64, and powerpc64le.

required flags.

* sysdeps/unix/sysv/linux/wordsize-64/pwritev64.: Likwise.
* sysdeps/unix/sysv/linux/x86_64/x32/syscalls.list (pwritev): Remove
syscall from auto-generation.
* sysdeps/unix/sysv/linux/pwritev.c: Rewrite implementation.
[WORDSIZE == 64] (pwritev64): Remove macro.
[!PWRITEV] (PWRITEV): Likewise.
[!PWRITEV] (PWRITEV_REPLACEMENT): Likewise.
[!PWRITEV] (PWRITE): Likewise.
[!PWRITEV] (OFF_T): Likewise.
[!__ASSUME_PWRITEV] (PWRITEV_REPLACEMENT): Likewise.
(LO_HI_LONG): Remove macro.
[__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (pwritev): Add function.
* sysdeps/unix/sysv/linux/pwritev64.c: Rewrite implementation.
(PWRITEV): Remove macro.
(PWRITEV_REPLACEMENTE): Likewise.
(PWRITE): Likewise.
(OFF_T): Likewise.
(pwritev64): New function.
