Of the changes in this commit, the changes in `HELPER(commit_hvx_stores)()`
are less obvious. They are required because of some macro invocations like
SCATTER_OP_WRITE_TO_MEM().
e.g.:
In file included from ../target/hexagon/op_helper.c:31:

The semantics for these instructions are present, but the encodings
are missing.
Note that these are treated as nops in qemu, so we add overrides.
