Prior to this change, both 0 and 1 as RNG seed would result in the same
internal state. state0 and state1 cannot both be zero, but murmur hash
maps 0 back to 0.

Since the generic GetCallingContext is deprecated, but there's still the
use case for the debugger to get the currently debugged context while in
the debug context, add a convenience API for it.
Note that EventDetails already exposes this context, but the embedder
might not necessarily have the EventDetails around.

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

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.

original commit message:
Introduce a dedicated Float64Log machine operator, that is either
implemented by a direct C call or by platform specific code, i.e.
using the FPU on x64 and ia32.
This operator is used to implement Math.log as a proper TurboFan
builtin on top of the CodeStubAssembler.
Also introduce a NumberLog simplified operator on top of Float64Log
and use that for the fast inline path of Math.log inside TurboFan
optimized code.

This causes OS compatibility information to be omitted which can lead
to strange behavior. This change adds a manifest to:

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.
