Tom Lane 7915a9515c Add RISC-V spinlock support in s_lock.h. 
Like the ARM case, just use gcc's __sync_lock_test_and_set();
that will compile into AMOSWAP.W.AQ which does what we need.

At some point it might be worth doing some work on atomic ops
for RISC-V, but this should be enough for a creditable port.

Back-patch to all supported branches, just in case somebody
wants to try them on RISC-V.
