Backport r265322 from llvm upstreamhjl/pr70155/gcc-6-branch
Since x86 psABIs require the function incoming stack must align at 16
bytes, child process stack passed to clone should be aligned at 16
bytes.
PR testsuite/70520
* c-c++-common/asan/clone-test-1.c (main): Align child process
stack to 16 bytes.
