    wrong code with points-to and volatile

caused


with GCC configured with

../../gcc/configure 
--prefix=/export/users/haochenj/src/gcc-bisect/master/master/r15-579/usr 
--enable-clocale=gnu --with-system-zlib --with-demangler-in-ld 
--with-fpmath=sse --enable-languages=c,c++,fortran --enable-cet --without-isl 
--enable-libmpx x86_64-linux --disable-bootstrap

To reproduce:

$ cd {build_dir}/x86_64-linux/libgomp/testsuite && make check 
RUNTESTFLAGS="c++.exp=libgomp.oacc-c-c++-common/acc_prof-kernels-1.c 
--target_board='unix{-m32}'"
$ cd {build_dir}/x86_64-linux/libgomp/testsuite && make check 
RUNTESTFLAGS="c++.exp=libgomp.oacc-c-c++-common/acc_prof-kernels-1.c 
--target_board='unix{-m32\ -march=cascadelake}'"
$ cd {build_dir}/x86_64-linux/libgomp/testsuite && make check 
RUNTESTFLAGS="c++.exp=libgomp.oacc-c-c++-common/acc_prof-kernels-1.c 
--target_board='unix{-m64}'"
$ cd {build_dir}/x86_64-linux/libgomp/testsuite && make check

(If you met problems with cascadelake related, disabling AVX512F in command 
line might save that.)
(However, please make sure that there is no potential problems with AVX512.)
