Replace divide with look-up This commit replaces an integer divide with a table-lookup. It is to improve decoding speed, and at the same time, to reduce possible complications with a bug in AMD Family 12h processors: "665 Integer Divide Instruction May Cause Unpredictable Behavior" Change-Id: I678b707a538798a923850bac467e66e847e6def7
