Add support for .set and .weak on AVR.
Fix 64 bit negation on AVR.

Added support for X,Y,and Z register aliases plus low/high forms, and post-incrementation in AVR assembler reader.
...
Cleaned up parameter and funcretloc information generation in AVR paramanger, and made it closer to GCC's calling convention.
Fixed a number of codegenerator bugs generating invalid or broken instructions: CP operands were swapped, a number of instructions had immediate operands, and stack frame epilogue wasn't complete.
Added a bunch of peephole optimizations that clears the generated code up a lot.
