Hexagon (target/hexagon) Add v68 scalar instructions
The following instructions are added
L2_loadw_aq
L4_loadd_aq
R6_release_at_vi
R6_release_st_vi
S2_storew_rl_at_vi
S4_stored_rl_at_vi
S2_storew_rl_st_vi
S4_stored_rl_st_vi
The release instructions are nop's in qemu. The others behave as
loads/stores.
The encodings for these instructions changed some "don't care" bits
L2_loadw_locked
L4_loadd_locked
S2_storew_locked
S4_stored_locked
