RISC-V has no support for subword atomic operations; code currently
generates libatomic library calls.
This patch changes the default behavior to fast inline subword atomic
calls that do not require libatomic.

While improving access path analysis a typo happened. Now it can happen
that gcc misscompiles. The patch is fixing the issue. However, also
other gcc versions 10.2+ are affected. They also should be bumped or the
fix should be backported.
