978acb8d5e Adjust the visibility of the standalone targets in the GN build.
As part of the migration from GYP->GN, we want to make sure that we
can track when new targets are added to either the GYP or GN builds
and that we are building everything we expect to build.

In GN, unlike GYP, if a build file gets referenced from other files,
building 'all' will cause every target to be built in it. This means in
particular, that we can end up trying to build targets that are not
necessarily intended to be visible to the rest of the build. To get
around this, any target that is defined but hidden (like 'v8_snapshot',
in V8's case) should still be visible to a top-level target called
"//:gn_visibility".

cf53fed972 Handle the case when derived constructor is [[Call]]ed with 0 args.
ArgumentsAdaptorStub for derived constructor (the one that needs
new.target) works in this way:
 - If the constructor is invoked via the Construct stub, we know that
   actual arguments always include new.target. ``arguments`` object
   however should not include a new.target, therefore we remove it.
   We achieve this by decrementing the argument count.
 - If the constructor is invoked as a call, we do not care for a correct
   ``arguments`` array since the constructor will immediately throw on
   entrance.
The bug is that the call could actually pass 0 actual arguments, but I
decrement unconditionally :(. The fix is to detect this case and avoid
decrementing. ``arguments`` is bogus, but it is ok as constructor
throws.

Long-term we should just remove mucking about with arguments for
new.target and just get it from the stack.

2a86d26f33 MIPS: Improve '[es6] When comparing two symbols we may need to throw a TypeError'.
Improve d26f5d3923

Original commit message:
When comparing a symbol to istself using <, <=, > or >= we need to
throw a TypeError. This is correctly handled in the runtime function
so if we are comparing a symbol fall back to use the runtime.

38f7ccba79 PPC: [turbofan] Fix tail call optimization.
Port d21de2a48b

Original commit message:
Tail calls are matched on the graph, with a dedicated tail call
optimization that is actually testable. The instruction selection can
still fall back to a regular if the platform constraints don't allow to
emit a tail call (i.e. the return locations of caller and callee differ
or the callee takes non-register parameters, which is a restriction that
will be removed in the future).

Also explicitly limit tail call optimization to stubs for now and drop
the global flag.

d6945db703 [turbofan] Add SimplifiedOperator::Allocate operator.

allocations, but still disabled because change lowering introduces
floating allocations outside the effect chain that interfere.
