objdump --mcpu=mosw65816 doesn't decode newer instructions about llvm-mos

More rigorous testing and this doesn't appear to be the case.

For example:

0000203a <main>:
    203a: a2 d7         ldx     #$d7
    203c: 86 82         stx     $82                     ; 0x82 <__rc2>
    203e: a2 20         ldx     #$20
    2040: 86 83         stx     $83                     ; 0x83 <__rc3>
    2042: 20 5a 20      jsr     $205a <puts>
    2045: ea            nop
    2046: 18            clc
    2047: fb            xce
    2048: ea            nop
    2049: ea            nop
    204a: ea            nop
    204b: 38            sec
    204c: fb            xce
    204d: a2 de         ldx     #$de
    204f: 86 82         stx     $82                     ; 0x82 <__rc2>
    2051: a2 20         ldx     #$20
    2053: 86 83         stx     $83                     ; 0x83 <__rc3>
    2055: 20 5a 20      jsr     $205a <puts>
    2058: 80 fe         bra     $2058 <main+0x1e>

Is indeed correct.
