+ allow access to absolute symbols with address type in inline assembler
* allow absolute addresses in avr inline assembler
+ tests

cf28b202eb * integrated the getintregister() implementation for 8-bit and 16-bit alus from

ddba821561 * GetNextReg(), used by 16-bit and 8-bit code generators (i8086 and avr) moved
from cpubase unit to a method in the tcg class. The reason for doing that is
  that this is now a standard part of the 16-bit and 8-bit code generators and
  moving to the tcg class allows doing extra checks (not done yet, but for
  example, in the future, we can keep track of whether there was an extra
  register allocated with getintregister and halt with an internalerror in case
  GetNextReg() is called for registers, which weren't allocated as a part of a
  sequence, therefore catching a certain class of 8-bit and 16-bit code
  generator bugs at compile time, instead of generating wrong code).
- removed GetLastReg() from avr's cpubase unit, because it isn't used for
  anything. It might be added to the tcg class, in case it's ever needed, but
  for now I've left it out.
* GetOffsetReg() and GetOffsetReg64() were also moved to the tcg unit.

3c96090d3c + optimized avr code generation for shr by shiftcount=size*8-1 and sar by
shiftcount>=size*8-1. This is commonly used by code, that extracts the sign
  bit and improves code generation for signed division by power-of-2 as well.
  This also fixes building avr-embedded (mantis #32241), which was caused by an
  infinite loop in the register allocator, when regvars are enabled, due to too
  much register pressure, when building charset.pp after r36842.
