1e28790e99 * fpc_PushExceptAddr's parameter Ft changed from LongInt to SmallInt on 16-bit CPUs for better efficiency

252903175c * TExceptAddr.frametype changed to SmallInt on 16-bit CPUs, since the compiler allocates 3*sizeof(pint) for the whole structure (and using longints on 16-bit CPUs is wasteful anyway)

ebe1d74d6e * Moved multiple similar checks for FPC_HAS_FEATURE_EXITCODE and FPC_LIMITED_EXITCODE to Halt() procedure. Now these checks appear only once.

56900b4754 * RTL: clean up exception handling code (functionality is not changed). 
* changed fpc_pushexceptobj to normal procedure, it does not need to be a compilerproc.

a32fdc3ae6 + Added a simple helper tcg.g_call, intended to replace allocallcpuregisters+a_call_name+deallocallcpuregisters sequence which is used all over the place. 
* Refactored code generation for tcgonnonde and tcgtryexceptnode, simplifying both compiler and generated code. Merged compilerprocs called in sequence into larger ones (fpc_popobjectstack+fpc_destroyexception -> fpc_doneexception, fpc_popsecondobjectstack+fpc_destroyexception+fpc_reraise -> fpc_raise_nested).

fcaac0ebe1 compiler,rtl - safecall handling: 
- pass address to SafeCallException  method(rtl needed a modification)
  - improve code generation for regular safecall routines (not methods)
  - improve test - check that passed exception and address are valid

b9f6efc85b + "compproc" helpers 
* renamed several helpers so that their name is the same as their
    "public alias", which should facilitate the conversion of processor
    specific code in the code generator to processor independent code
  * some small fixes to the val_ansistring and val_widestring helpers
    (always immediately exit if the source string is longer than 255
     chars)
  * fixed fpc_dynarray_high and fpc_dynarray_length if the dynarray is
    still nil (used to crash, now return resp -1 and 0)
