Taylor Simpson a5a8d98c85 Hexagon (target/hexagon) fix l2fetch instructions
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.

Test case added to tests/tcg/hexagon/misc.c
