Support for x64 builds with optimizing compiler

Description

Add support for x64 to the optimizing compiler.

Some remaining TODOs:

  • Fix bugs

  • Review decision to keep int-typed values in registers (and never spill them)

  • Enable opt compiler to use more registers for register allocation on x64

  • Testing

  • Improve performance
