4cf2a2672a changes to fix #32043 
* changed most of the variables in the assembler readers used to store constants from aint to tcgint 
  as aint has only the size of the accumular while some CPUs (AVR) allow larger constants in instructions
+ allow access to absolute symbols with address type in inline assembler
* allow absolute addresses in avr inline assembler
+ tests

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol(): 
it was AT_NONE, which is invalid and should never be used
  * explicitly pass the correct value for all calls to those methods elsewhere
    in the compiler

f69f6336e9 * Replaced hacks with resetting 'c' to zero and decreasing inputpointer by boolean parameter to skipcomment and skipoldtpcomment. This parameter specifies whether first character of comment should be read. 
- in_asm_string also rendered useless by r32828, removed.

92e7c0b03f m68k: assembler reader changes 
* don't reimplement BuildStringConst, use the inherited one
* findopcode's string argument is now const, simplified the function and removed some dead code
* removed an intentional null ptr write in an error path, which was debug code and left in accidentally

bbfbab7e0c * Moved handling of comments and line breaks in assembler blocks from scanner to tokenizer level. Handling them at character level was causing compiler to accept comments in the middle of any assembler token, which should never happen. It was also causing Mantis #27459: a newline immediately after closing 'end' token was first handled in asmgetchar and then by normal parser, causing all subsequent line numbering to be off by one.

cfe13734e0 * m68k: Fixed damage caused by r27573 and r28177: 
* longjmp: restored loading of function result (d0) which got removed in r28177.
  * While at the point, added test for zero, because longjmp must never return zero values.
  * Assembler reader: 'fp' refers to frame pointer, not the stack pointer.

d2995cbf14 - Removed ConcatPasString procedure, it duplicates ConcatString (it the past they probably used to differ, but today both preserve null characters).

05fc3bc427 * m68k/ra68kmot.pas, tm68kmotreader.gettoken: 
if "firsttoken" isn't set we must not take the possibility into account that the token could be an opcode

ca6ca31953 The message scan_f_illegal_char seems to have gained additional parameters since it was 
introduced. Take that into account to avoid an access violation.

e87f0e1df4 m68k/ra68kmot.pas, tm68kmotreader.Assemble: 
the asmr_d_*_reading messages need an argument which specifies in which style the assembler code
  is read; this is most importantly used on i386; on m68k we currently don't have multiple styles,
  so simply disable these messages

0fc422f244 * moved definition of maxcpuregister and tcpuregisterset from cgbase to 
cgutils, and define them so they are no larger than what is required by
    the current target platform
  * added cgutils to the uses clause of several units that use the
    tcpuregisterset type
