39c48f0d01 * Fixed r43577 for cases when the size of the new result of a simplified node after typecheckpass is smaller than the size of the original node's result. This caused internal errors or invalid assembly in some cases. Issue #36587.

0d96963459 * Do not promote integer comparison operations to native size if one side is a constant and its value is within range of opposite side. Instead, cast the constant to type of the opposite side. 
Comparisons are already not promoted if sides are equally signed, but this wasn't true for "unsigned vs constant" case, because constants are preferably parsed as signed.
The change considerably improves generated code for i386 and even more considerably for m68k. Tested on i386-win32.

e80ecd4d5b + moved handling of pointer comparison in pass_1 to new virtual method 
taddnode.first_cmppointer. To be overriden for i8086 huge pointer comparisons.

da77535631 * the handling of pointer arithmetic in pass_1 moved to a new virtual method 
taddnode.first_addpointer. This will be overridden in the i8086 code generator
  in order to implement huge pointer arithmetic.

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls
