5cf0a20d4f This is purely a formatting patch that gets us closer to the mecca of fitting

97abe28059 This purely mechanical patch gives the "I" tblgen class operand list and asm 
string operands, and adjusts all users to pass them in instead of using II.

with an incremental approach rather than a revolutionary approach.

e3d3cd3e71 Fix cases where we generated horrible code like this: 
mov %EDI, 12
        add %EDI, %ECX
        mov %ECX, 12
        add %ECX, %EDX
        mov %EDX, 12
        add %EDX, %ESI

instead (really!) generate this:

        add %ECX, 12
        add %EDX, 12
        add %ESI, 12
