8b9e90dc7a * keep track of whether a routine has a C-style variadic parameter in the 
procoptions even when it's through an array-of-const parameter
  * always call create_varargs_paraloc_info() instead of create_paraloc_info()
    in the former case, even when no varargs parameters are specified (because
    on some platforms even some non-variadic parameters need to be passed
    differently, such as on ARM with gnueabihf)

122d0d36d6 + volatile() expression that marks an expression as volatile 
* disable matching volatile references in the assembler optimisers, so they
    can't be removed (more conservative than needed, but better than removing
    too many)
   o the CSE optimiser will ignore them by default, because they're an unknown
     inline node for it
  * also removed no longer used fpc_in_move_x and fpc_in_fillchar_x inline node
    identifiers from rtl/inc/innr.inc, and placed fpc_in_unaligned_x at the
    right place

4cd6f59bc3 * changed create_hlcodegen into a procvar, so that we don't have to insert 
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
   o prevents dependency cycles that can cause llvm codegen units to init
     before the cpu variants, which is bad since the llvm versions have to
     override the cpu variants in their init code (+ added checks in the
     init code that they are in fact initialised later)

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.

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

"don't free even if not registered"; use for defs that may not be written

  * mark all defs created for para locations as "don't free even if not
    registered", because we don't discard and recalculate all para locations
    after a module has been compiled (since that's not needed)
   o solves issues if the paralocations for a routine in the interface of
     unit A are calculated while the implementation of unit B gets
     compiled, and a new reusable type is allocated at that point which
     is not used anywhere else (after r32160)
