  1. Add Ssdtso extension 

    The Ssdtso extension adds a DTSO bit to the {m,s,h}envcfg
registers to enable TSO. Since Spike is sequentially consistent
it always operates TSO-compatible. Therefore, all we have to do
is make Spike aware of the extension (reading and writing the
{m,s,h}envcfg register already exists and we don't use the bit
inside of Spike anywhere).

For completeness, this patch also defines the {M,S,H}ENVCFG_DTSO
mask macros, even if they are not used anywhere.
