This makes the isolate-driver script rebase all paths to be
relative to the isolate-file location. This is an assumption
of the go binaries and is needed for batcharchive to work.

In gyp, actions were executed relative to the gyp file that
specified them, while in gn it's relative to the product dir.

This makes sure {NodeProperties::FindFrameStateBefore} can deal with
effect chains that are marked as dead. This can happen when reducers
looking for frame states run together with other reducers killing some
execution paths within the same reduction phase.

This calls the action that archives test262 in gn. In gn
we can't specify an action output outside the product
directory. This works around it with an extra action
stamp file in the product directory, while the archive
remains in the test directory.

We don't want to generate the archive in the product
directory, as some legacy archiving scripts might include
it and it's too large. It should only be included in the
swarming tasks that are going to use it for testing.

Make sure to flatten strings first in JSON.parse() builtins, otherwise
we always hit the slow path for non-sequential strings, i.e. for cons
strings.

Also don't create any arguments adaptor frames for JSON.parse() as the
C++ builtin can handle any number of inputs properly.

This moves processing of jumps out of bytecode array builder and into
bytecode array writer. This simplifies the pipeline by avoiding having
to flush for offset and patch up offsets in bytecode array builder based
on what was emitted by the bytecode array writer.

This also enables future refactorings to add dead code elimination back
into the pipeline, and move processing of scalable operand sizes to the
end of the pipeline (in the bytecode array writer) rather than having to
deal with scalable operand types throughout pipeline.
