c3ef42b164 * allow cmov with memory reference if it is a pure symbol or a rip relative symbol: as the symbol is 
allocated within the image of the program, this should never cause a seg. fault, so it is save
    to use cmov with it

122d0d36d6 + volatile() expression that marks an expression as volatile 
* disable matching volatile references in the assembler optimisers, so they
    can't be removed (more conservative than needed, but better than removing
    too many)
   o the CSE optimiser will ignore them by default, because they're an unknown
     inline node for it
  * also removed no longer used fpc_in_move_x and fpc_in_fillchar_x inline node
    identifiers from rtl/inc/innr.inc, and placed fpc_in_unaligned_x at the
    right place
