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

210ffe4b77 Improve codegen for the LLVM offsetof/sizeof "operator". Before we compiled
this LLVM function:

int %foo() {
        ret int cast (int** getelementptr (int** null, int 1) to int)
}

into:

foo:
        mov %EAX, 0
        lea %EAX, DWORD PTR [%EAX + 4]
        ret

now we compile it into:

foo:
        mov %EAX, 4
        ret

This sequence is frequently generated by the MSIL front-end, and soon the malloc lowering pass and
Java front-ends as well..
