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

4cd6f59bc3 * changed create_hlcodegen into a procvar, so that we don't have to insert 
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
   o prevents dependency cycles that can cause llvm codegen units to init
     before the cpu variants, which is bad since the llvm versions have to
     override the cpu variants in their init code (+ added checks in the
     init code that they are in fact initialised later)

4686f61002 * keep track of the temp position separately from the offset in references,

518cdf9674 * replaced the saved_XXX_registers arrays with virtual methods inside 
tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
  new methods are called get_saved_registers_XXX, where XXX is the register
  type ("int", "address", "fpu" or "mm")
