Hexagon (target/hexagon) Add overrides for count trailing zeros/ones
The following instructions are overriden
S2_ct0 Count trailing zeros
S2_ct1 Count trailing ones
S2_ct0p Count trailing zeros (register pair)
S2_ct1p Count trailing ones (register pair)
These instructions are not handled by idef-parser because the
imported semantics uses bit-reverse. However, they are
straightforward to implement in TCG with tcg_gen_ctzi_*
Test cases added to tests/tcg/hexagon/misc.c
