d05adbcdce 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.

* Change grammar to require a const before a local constant definition

4cecdd206e 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".
