6b43705437 * fixed compiler internal error when the in_not_assign_x/in_neg_assign_x are 
applied to a LOC_REGISTER variable

256dc546ac + implemented the in_neg_assign_x and in_not_assign_x inline nodes, which will 
be used (TBD in a future commit) for optimizing x:=-x and x:=not x on CPUs
  that support performing these operations directly in memory (such as x86)

8024fcd7ec * if an operator overload in a structured type is invalid print an error only for the declaration and not the implementation as well 
This fixes Mantis #31634 as far as I see it useful to; anything further would probably require extension of the message generation system by a context or such so that the compiler could write "Error in TFoo<Integer>: ..." instead of merely "Error: ..." or something like that.
No test added due to the nature of the bug.

1560f20e7f + implemented other 32-bit rol/ror by const methods for i8086 and added a

0fd860d9e7 * refactored the code generation for 32-bit rol/ror by const for i8086, so it 
uses less code repetition and allow choosing various methods (some of which
  will be implemented later and selected, according to the cpu and optimization
  settings (size vs speed))

0b1a54f924 * on 16-bit CPUs, avoid the unnecessary 32-bit conversion of the right shl/shr 
parameter, when the operation is 32-bit (even when the operation is 32-bit,
  the shift count is only 16-bit on 16-bit CPUs, so using 32-bits is wasting an
  extra register and an extra instruction to initialize it)

6580dfee39 * generate better i386 code for 64-bit shl/shr, by masking the shift count by 
63, instead of comparing it to 64 and branching. Note that, although this
  changes the behaviour of 64-bit shifts by values larger than 64 (when stored
  in a variable), it actually makes them consistent with both the code,
  generated on x86_64, as well as with 64-bit shift by constant on i386 itself.

f29492bdea * at -O3 level, convert i:=i and/or/xor k to the new in_[and/or/xor]_assign_x_y 
inline nodes, which should generate better code for certain CPU targets,
  including x86. Note that the optimization isn't applied yet for all integer
  types (those that have extra implicit typecasts, inserted by the compiler,
  aren't handled yet).

fc59649a98 + added inline nodes for handling and/or/xor in place (i.e. x:=x op y, where 
op=and/or/xor). They generate more optimal code on certain architectures
  (including x86). The new inline nodes aren't generated by the compiler yet,
  but will be used in the future, at certain optimization levels, whenever the
  pattern x:=x op y is detected by the compiler.
