* ConstPoolPointerReference now represents a pointer to a GlobalValue
* Methods name references are now explicit pointers to methods
* Rename Value::GlobalVal to Value::GlobalVariableVal to avoid confusion

%ListNode3 = global %list { %list* null, int 4 }

because %list is name and the parser expected a literal {..} type there.

In addition, simplified rules that the fix (Allow any Types there, not just a StructType)
made obsolete.  Simplified type propogation a bit.

* Allow multiple definitions of a type with the same name as long as they are the same type
* Eagerly resolve types to allow #2 to work instead of after the whole const pool has been processed
* Change grammar to require a const before a local constant definition

(1) Avoid hard-coding some register numbers.
(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
    into the immed field of the copy machine instruction, then
    generate a load-constant instead of a copy.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".

(1) Ensure that delay slot instructions are not moved out of place (this
    was happening for some CALL instructions).  Basically, we need to
    move all delay slot instructions out of the graph and handle them
    along with the delayed control transfer instruction.
(2) Mark scheduled instructions correctly when instructions are scheduled
    in more than one cycle in a single step (due to delay slots).
