d77a1bbc2f Corrected call interference bug - suggested color not allocated if 
volatile and there are call interferences

6c697526bf 1. Move most of the constant-fixup code into machine-independent file 
InstrSelectionSupport.cpp.  It now happens in a bottom-up pass on
   each BURG tree after the original top-down selection pass on the tree.
2. Handle global values as constants (viz., constant addresses).

1a176f15dc Make the sparc.burg file be a little more flexible and rubust in the fact of 
renumbering of instructions.  It is still horribly broken and grossly dependant on the number of instructions, but now it is a least a little better.

Oh yeah it also works now.

3652ef7587 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".

514180ed83 Make class TargetMachine the common interface to all target-dependent

more uniformly.
