6bc105a7b9 Add binary emission stuff for VLDM/VSTM. This reuses the 
"getRegisterListOpValue" logic. If the registers are double or single precision,
the value returned is suitable for VLDM/VSTM.

2ac190238e add fields to the .td files unconditionally, simplifying tblgen a bit. 
Switch the ARM backend to use 'let' instead of 'set' with this change.

future to separate out the ia, ib, da, db variants of the load/store multiple
