     Remove the logical stmt cache for now.

FAIL: libgomp.c++/task-reduction-8.C execution test

with GCC configured with

../../gcc/configure 
--prefix=/local/skpandey/gccwork/toolwork/gcc-bisect-master/master/r12-1053/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.c++/task-reduction-8.C --target_board='unix{-m32\ 
-march=cascadelake}'"

I've been getting spurious failures in all the libgomp.c++/ task-reduction-X testcases since before any of my patches were checked in.   passing sometimes, failing others.

Since that code being removed is not in use, I doubt that is actually the root cause.
