efc5e339d0 * use an enum instead of integer constants to represent inline numbers 
* compinnr.inc include file converted to a unit
* inline number field size stored in ppu increased from byte to longint
* inlines in the parse tree (when written with the -vp option) now printed with
  their enum name, instead of number

179c1ab328 * changed ttemp*node.tempinfo^.flags to a private field, and added setters 
and getters for the ttemp*node classes instead
   o this will allow descendants to prevent certain flags from being added
     or removed. E.g. for LLVM, certain temps must never be put in registers
     because it cannot typecast a value in a register from a non-record/array
     type to an array type without forcing it to memory (so if that is done
     on an lvalue, the result will be written to the memory temp instead of
     to the register)

86bde57b0f * do not switch around node subtrees if they have different resultdefs, e.g. 
because a subtree has been optimized for a 32x32->64 multiplication (so
   some subtrees have a 32 bit resultdef and others a 64 bit resultdef)

ae56841ee6 * do not apply node CSE to nested loads on high level cpu targets, because 
their nested tree already contains the load (subscriptn) for the variable
    itself and there is no clean/easy way to avoid that in a completely
    portable way in ncgnstld + test
