ce22ec1251 * 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

disables an implicit rule that has LOCAL_CFLAGS as a prerequisite.

for argument passing, that instruction is directly added to the InstructionsBefore
set of the called machine instruction - i.e., it is not reordered.
