51e68eb302 * fixed several places where the interface crc could change: 
o unsetting po_inline while parsing the implementation for various reasons
     (interprocedural goto/label, accessing a local in a parent frame,
      having nested procedures)
   o instead handle this via the pio_inline_not_possible flag
   o noreturn can no longer be specified only in the implementation

d1fc31de94 + add support for '[' and ']' parenthesis in addition to '(' and ')' in 
rautils.TExprParse. They behave exactly like '(' and ')'. However, you cannot
  nest '(' with ']' and '[' with ')'. This is introduced in order to help
  implementing support for BP7 asm constants that are parsed like references,
  e.g. 'dd Rec.Str[5]' or 'dd 5[7]'.

b9e41330d4 + ensure the callee size paraloc info is available, when setting up a local var 
or parameter in RAUtils.TOperand.SetupVar(). This fixes a compiler crash, when
  a parent parameter or local var is accessed (in certain ways) inside a nested
  inline asm routine.

9450beb99c * fixed bug in intel syntax i8086 inline asm, when certain 'jmp/call [v]' 
instructions got erroneously converted to 'jmp/call v', if 'v' is an external
  far variable that points to certain things (like a local label, exported via
  public)

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

744facb7fc * properly support accepting register parameters of assembler routines in 
the intel assembler reader: no longer parse them as register tokens,
    but as local operands that are later converted into registers. This
    ensures in particular that the type of the operand is set, which is
    necessary in case this operand later subscripted (as in tasm10a)

aa82e00615 * fixed check to determine whether a record parameter can be subscripted 
directly in inline assembly: that's only possible if it's a register
    parameter where the address of the record was passed (rather than the
    record itself), or if a parameter has been explicitly typecasted in
    Intel-style assembly using ".size"

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol():

42d251da1c - x86 assembler readers: cleaned out operand swapping code. Operands of TInstruction are kept in AT&T order, Intel reader attaches operands right-to-left. It was effectively the same way before the change (except Intel reader attaching operands left-to-right, followed by a single swap), operand order checks all over the place were just reducing readability.
