match: Check the number of elements in broadcasting operands

The broadcasting decorator {1to##} must describe exactly how many times
the memory element is repeated in order to clearly match the correct
instruction format.

For example,
    vaddpd zmm30,zmm29,QWORD [rdx+0x3f8]{1to8}   ; good
    vaddpd zmm30,zmm29,QWORD [rdx+0x3f8]{1to16}  ; fail qword * 16 = 1024b

    vaddps zmm30,zmm29,DWORD [rcx]{1to16}	 ; good
    vaddps zmm30,zmm29,DWORD [rcx]{1to8}	 ; fail dword * 8 = 256b
