Almost all occurrences of "bytecode" in the sources have been eliminated.

ea859be53c Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits from 
TargetLowering to SelectionDAG so that they have more convenient
access to the current DAG, in preparation for the ValueType routines
being changed from standalone functions to members of SelectionDAG for
the pre-legalize vector type changes.

8dd86c14d4 More effective breakdown of memcpy into repeated load/store. These are now 
in the order lod;lod;lod;sto;sto;sto which means the load-store optimizer
has a better chance of producing ldm/stm.  Ideally you would get cooperation
from the RA as well but this is not there yet.
