(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".

916f962d8b Make class TargetMachine the common interface to all target-dependent
information, including instr, sched, and reg information.
This allows us to allocate them all in one place and use them much
more uniformly.

d6a98c11bc Chris seems fond of #include <vector>. Fix these. Also convert use list in
Value to a vector instead of a list.

7e70cdb641 Checkin changes to:
1. Clean up the TargetMachine structure.  No more wierd pointers that have to
   be cast around and taken care of by the target.
2. Instruction Scheduling now takes the schedinfo as an argument.  The same
   should be done with the instinfo, it just isn't now.
