e059ee832c Don't back past debug info intrinsics; SCEVExpander's strategy 
for ignoring debug info intrinsics everywhere else is to advance
past them, and it needs to be consistent.

df9a4f0591 Fix VLDMQ and VSTMQ instructions to use the correct encoding and address modes. 
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.
