Brian Cain 20c34a9216 target/hexagon: fix some occurrences of -Wshadow=local 
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:
    ../target/hexagon/mmvec/macros.h:205:18: error: declaration of ‘i’ shadows a previous local [-Werror=shadow=compatible-local]
      205 |         for (int i = 0; i < sizeof(MMVector); i += sizeof(TYPE)) { \
          |                  ^
    ../target/hexagon/op_helper.c:157:17: note: in expansion of macro ‘SCATTER_OP_WRITE_TO_MEM’
      157 |                 SCATTER_OP_WRITE_TO_MEM(uint16_t);

Y4_l2fetch == l2fetch(Rs32, Rt32)
Y5_l2fetch == l2fetch(Rs32, Rtt32)

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.
