X87: [compiler] Remove CodeStub from CompilationInfo.

  port d1d0196473e6919b222bf98a9fd9093805a5c5bc (r33410)

  original commit message:
  The motivation for this is that CompilationInfo really shouldn't
  explicitly know anything about CodeStubs. This is evident in
  the TurboFan stubs pipeline, which only needs to pass down
  information about Code::Flags to the code generator and not
  any of the CallInterfaceDescriptor silliness that Hydrogen has
  to push around, since TF has the Linkage class that
  encapsulates everything that is needed for the stub ABI. So,
  instead of threading CodeStub machinery through the TF stub
  pipeline, it is now removed from CompilationInfo and replaced
  by only the explicit bits needed both by the Crankshaft and
  TF pipelines in code generation.
