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..

f8f753f04b * Add support for indexing into structures, thanks to Chris (x86) 
The large diff is because of indentation of a whole region
* Fix querying predecessor blocks in SelectPHINodes(), thanks to Brian (v8)
* Add support for external functions malloc() and free()
* Fix some code indentation

Remember, kids: It's not plagiarism if you "creatively borrow" from your
sources.  It's called "research"!
