Interpreter_LoadStorePaired: Generate a program exception if non-indexed paired-single load/stores are used and HID2.LSQE is not set

Browse source 
HID2.LSQE is the Load/store quantize enable bit for non-indexed format
instructions (which are psq_l, psq_lu, psq_st, and psq_stu). If this bit
is not set and any of these instructions are attempted to be executed,
then a program exception is supposed to occur.
