skip using gcc brace groups for STMT_START/END

This warns (and warns a lot) on clang, and since these are documented
to only work to make a single statement, so there's little value to
allowing them to work in an expression.

An alternative would be to disable GCC brace groups on clang, but
these are used extensively in DEBUGGING builds to add extra checks
in sv.h.
