3fb79e61c2 Fix cute little bug that was causing the last 
structure offset to be ignored in computing an offset!

64f7567391 Small changed to printing a machine operand - It the operand is a def, it prints 
a star after it - only for debugging

0cd962fa61 * Change ExpressionConvertableToType to more closely match map behavior of 
ConvertExpressionToType
* Make ValueHandle's remove instruction from maps when they are deleted so that
  no false map hits occur if a subsequent instruction is allocated to the same
  space in memory.  This was a VERY VERY VERY EVIL NASTY BUG to track down. :-P

6e9422e14c 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.

value from size *before* subtracting size from offset!

097b7cb52a Distinguish LOCAL_LDFLAGS and LOCAL_LCFLAGS from LOCAL_CFLAGS. 
In particular, never put -lm in LOCAL_[L]CFLAGS because it
disables an implicit rule that has LOCAL_CFLAGS as a prerequisite.

24e29431bc 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.

c189997516 For phi elimination, now we are generating only one instruction 
using cpValue2Value instead of
passing vector to createCopyInstructionByType.

03fae5e5db Eliminate most uses of the machine instruction vector for each LLVM instr, 
since some m. instr. may be generated by LLVM instrs. in other blocks.
Handle non-SSA (anti and output) edges and true edges uniformly by
working with machine instructions alone.
