This used to be part of bug 829602 but I am breaking that bug up because it proved to be too large.

clang 3.2 gives me this:

/home/njn/moz/mi9/js/src/vm/ParallelDo.cpp:507:32: error: variable has
      incomplete type 'js::ion::ParallelCompileContext'
        ParallelCompileContext compileContext(cx_);
                               ^
../ion/Ion.h:22:7: note: forward declaration of
      'js::ion::ParallelCompileContext'
class ParallelCompileContext; // in ParallelArrayAnalysis.h
      ^

GCC 4.7 complains too:

/home/njn/moz/mi9/js/src/vm/ParallelDo.cpp: In member function ‘js::ion::MethodStatus ParallelDo::compileForParallelExecution()’:
/home/njn/moz/mi9/js/src/vm/ParallelDo.cpp:507:50: error: variable ‘js::ion::ParallelCompileContext compileContext’ has initializer but incomplete type
SelfHosting.cpp

You have this:

  #if defined(JS_THREADSAFE) && defined(JS_ION)
  #include "ion/ParallelArrayAnalysis.h"
  #endif // THREADSAFE && ION

Looks like the |defined(JS_THREADSAFE) &&| part needs to be removed.  r=me to do so, thanks.

Uplifted to m-c to un-break our fuzzers.
