b1e6823bc1 Fixed a bug concering LR spilling. Earlier, added spilled code was not inserted
into the instruction stream correctly.

71a0797f80 * 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

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.

a503b77130 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.

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.

d6c5e0f535 For phi elimination, now we are generating only one instruction
using cpValue2Value instead of
passing vector to createCopyInstructionByType.

624846d3fd 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.

0b0bd6e749 Only add true dep. edges from an earlier to a later instruction.
This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!
