Also drop the DEFINE_FLAGS() macro, and use the typedef explicitly.

original commit message:
  Refactoring InterfaceDescriptors away from code-stubs.h

  Clean up and create seperation between the concept of a call descriptor and a
  code stub interface descriptor. The former is just concerned with how to call,
  but the latter has many extra hints related to code generation and deoptimization
  for the implementation of a particular code stub.

Addition supports lhs immediates by commuting. Subtraction supports only zero

The "enum hack" (see Item 2 of "Effective C++") is the only known
portable way to define constant integral values within template
classes. Fixes the weird work-arounds required for certain GCC
versions.

Two improvements:
- At phi nodes, we now try to merge operands into one spill slot and
  then reuse the spill slot for the phi.
- After register allocation we merge disjoint spill slots.

With this change, I see about 4% improvement in zlib.
