Bring in some patches from the head of GCC's CVS back to the latest

released version, 3.4.3.  This mainly adds support for new AVR devices
that appeared on the market recently, and fixes a bug related to the
order of assignments for volatile uint16_t * objects (in the
assumption they might point to IO space where the order of two 8-bit
operations can be important).
