We now want to run the tests with --nouse-is and --nolazy, as well as using
these flags when debugging the code generator.  Should we put the changes in
Scons, or in test.py, or as temporary platform-specific changes in
flag-definitions.h?  Or just type in the flags every time we run?

Line 216: movq(target, code, RelocInfo::EXTERNAL_REFERENCE);  // Is external
reference?
No, a Code object is an embedded object or code target (or possibly some third
kind of target). External reference is for non-heap locations.
In this case it's RelocInfo::EMBEDDED_OBJECT, to match the ia32 macro-assembler
which uses Immediate(code) (always becomes embedded object for heap objects).

Put the flags in every time we run (and make local shell scripts to help
ourselves).
