0cedab9a0d Neon does not actually have VLD{234}.64 instructions. 
These operations will have to be synthesized from other instructions.

70cd88fb7b Add a new pre-allocation pass to assign adjacent registers for Neon instructions 
that have that constraint.  This is currently just assigning a fixed set of
registers, and it only handles VLDn for n=2,3,4 with DPR registers.
I'm going to expand it to handle more operations next; we can make it smarter
once everything is working correctly.
