- O2, enums, and switch statements work in romcc

- Support for compiling romcc on non x86 platforms
  - new romc options -msse and -mmmx for specifying extra registers to use
  - Bug fixes to device the device disable/enable framework and an amd8111 implementation
  - Move the link specification to the chip specification instead of the path
  - Allow specifying devices with internal bridges.
  - Initial via epia support
 - Opteron errata fixes
