In the encoding groups * floating-point data-processing (1 source) * floating-point data-processing (2 source) * floating-point data-processing (3 source) * floating-point immediate * floating-point compare * floating-ponit conditional compare * floating-point conditional select bit 31 is M and bit 29 is S (and bit 30 is 0, already checked at this point in the decode). None of these groups allocate any encoding for M=1 or S=1. We checked this in disas_fp_compare(), disas_fp_ccomp() and disas_fp_csel(), but missed it in disas_fp_1src(), disas_fp_2src(), disas_fp_3src() and disas_fp_imm(). We also missed that in the fp immediate encoding the imm5 field must be all zeroes. Correctly UNDEF the unallocated encodings here.
