AllocInfo.Instruction becoming an int.

#-1. Other minor changes to deal with AllocInfo.Instruction becoming an int.

(Instruction #-1's operands = argument list).

They just want to provide the information in differing ways.

using an edge profile to produce block counts gives the exact same numbers
as using a block count directly.

come up a lot in the code generated by the C++ front-end for pointers
to member functions.  See PR166.

This is one small step towards the complete obliteration of
ConstantPointerRef's entirely!! Woot!

testcase like this:

int %test(int* %P, int %A) {
        %Pv = load int* %P
        %B = add int %A, %Pv
        ret int %B
}

We now generate:
test:
        mov %ECX, DWORD PTR [%ESP + 4]
        mov %EAX, DWORD PTR [%ESP + 8]
        add %EAX, DWORD PTR [%ECX]
        ret

Instead of:
test:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %ECX, DWORD PTR [%ESP + 8]
        mov %EAX, DWORD PTR [%EAX]
        add %EAX, %ECX
        ret

... saving one instruction, and often a register.  Note that there are a lot
of other instructions that could use this, but they aren't handled.  I'm not
really interested in adding them, but mul/div and all of the FP instructions
could be supported as well if someone wanted to add them.
