4686f61002 * keep track of the temp position separately from the offset in references,

cf28b202eb * integrated the getintregister() implementation for 8-bit and 16-bit alus from 
the avr and i8086 code generators into the base tcg class (so it can be reused
  by other 8-bit and 16-bit targets)

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.

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now
