Log Message:
Backport improvements into GCC's sanitizer_linux.cc from more recent LLVM

Backport fixups for syscall()/__syscall() routines from LLVM compiler-rt
dated October 1st 2018. The commit beffore switching LLVM compiler-rt
sycall calls to libc calls for NetBSD.

GCC8 will get part of these changes from upstream and GCC9 will operate on
libc calls directly for the NetBSD port.

This is intended to correct misuse of parameters of syscall()/__syscall()
that could break !x86 ports in UBSan.
