--- Comment #1 from John Brawn <john.brawn.123 at gmail.com> ---
This was fixed by http://reviews.llvm.org/rL183011, and with latest trunk
llvm-mc I get

echo 0x80 0xec 0x03 0x0b | llvm-mc -triple thumbv7 -show-encoding -disassemble
-show-inst
    .text
    fstmiax    r0, {d0}                @ encoding: [0x80,0xec,0x03,0x0b]
                                        @ <MCInst #122 FSTMXIA
                                        @  <MCOperand Reg:66>
