[PATCH v4 03/30] target/arm: Rename TBFLAG_ANY, PSTATE_SS

[Richard Henderson]

We're about to rearrange the macro expansion surrounding tbflags,
and this field name will be expanded using the bit definition of
the same name, resulting in a token pasting error.

So PSTATE_SS -> PSTATE__SS in the uses, and document it.
