Add some missing isel predicates on def : pat patterns to avoid generating VFP vmla / vmls (they cause stalls). Disabling them in isel is properly not a right solution, I'll look into a proper solution next.

It is only supported for ARM code.  Normally Thumb2 code would use DMB instead,
but depending on how the compiler is invoked (e.g., -mattr=-db) that might be
disabled.  This prevents a "cannot select MEMBARRIER_MCR" error in that
situation.  Radar 8644195

* LDM, et al, uses a bit mask to indicate the register list.
* VLDM, et al, uses a base register plus number.

The LDM instructions may be non-contiguous, but the VLDM ones must be
contiguous. Those are semantic checks that should be done later in the
compiler. Also postpone the creation of the bit mask until it's needed.
