Clean up parser, fix a bug that prevented this from working:
...
%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.

Several fixes:
...
(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".

Bug fixes:
...
(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).
