into the instruction stream correctly.

00521d79bf When allocating space on stack for writing a register, 
use the size of the register, not the size of the Value type,
to get the right alignment.

91014f6b0c Canged ColorCallArg so that when a call arg is directly pushed on to stack 
for argument passing, that instruction is directly added to the InstructionsBefore
set of the called machine instruction - i.e., it is not reordered.

6d35326cd5 1. Add a bottom-up pass on BURG trees that is used to fix constant operands. 
Needs to be bottom up because constant values may be forward-substituted

2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.

0714e3bc44 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.
