af9c0a766a 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.

67478b7484 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.

a7383895cd Fix bugs in FITOS/D instruction generation. 
The space for optional args in the stack frame is now being computed,
so finish the code generation for the variable `alloca'.
Finally, made a major overhaul of how stack frame is managed.

cb87df31db Fixed instruction information for RDCCR and WRCCR. 
Fixed selection to create a TmpInstruction for each integer CC register
(since it is an implicit side-effect, unlike FP CC registers which are
explicit operands).
