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
