- Fix VLDMQ and VSTMQ instructions to use the correct encoding and address modes. · 59f75bba
  Bob Wilson authored Mar 23, 2010
```
These instructions are only needed for codegen, so I've removed all the
explicit encoding bits for now; they should be set in the same way as the for
VLDMD and VSTMD whenever we add encodings for VFP.  The use of addrmode5
requires that the instructions be custom-selected so that the number of
registers can be set in the AM5Opc value.
