The two tests in question got a lot slower and started to timeout now that the C++ fallback implementation of the %Arguments intrinsics is composable with respect to inlining.

This removes the aforementioned flag which has been on by default for a while now. Note that this does not control optimization decisions, only the last-resort bailout in the graph builder.

There are now two runtime entries %NewClosure and %NewClosure_Tenured, with the same signature (one parameter, the SharedFunctionInfo, and the context of the caller). Also remove the HFunctionLiteral special case instruction from Crankshaft, as HCallWithDescriptor with FastNewClosureStub or HCallRuntime with either %NewClosure or %NewClosure_Tenured can easily do that for you. Also remove the redundant context parameter from the JSCreateClosure operator, because every JS operator already takes a context input.

port b37907ff (r30648). original commit message: The number of actual arguments should always be available, there's no point in trying to optimize away a simple assignment of an immediate to a register before some calls. The main motivation is to have a consistent state at the beginning of every function. Currently the arguments register (i.e. rax or eax) either contains the number of arguments or some random garbage depending on whether the callsite decided that the callee might need the information or not. This causes trouble with runtime implementations of functions that do not set internal_formal_parameter_count to the DontAdaptArguments sentinel (we don't have any of those yet), but also makes it impossible to sanity check the arguments in the callee, because the callee doesn't know whether the caller decided to pass the number of arguments or random garbage.

port ccbb4ff0 (r30629) original commit message: The new Call and CallFunction builtins supersede the current CallFunctionStub (and CallIC magic) and will be the single bottleneck for all calling, including the currently special Function.prototype.call and Function.prototype.apply builtins, which had handwritten (and not fully compliant) versions of CallFunctionStub, and also the CallIC(s), which where also slightly different. This also reduces the overhead for API function calls, which is still unnecessary high, but let's do that step-by-step. This also fixes a bunch of cases where the implicit ToObject for sloppy receivers was done in the wrong context (in the caller context instead of the callee context), which basically meant that we allowed cross context access to %ObjectPrototype%.

port db2ba190 (r30634). original commit message: The semantics of the %_CallFunction intrinsic seem to be very unclear, which resulted in a lot of bugs. Especially the combination with %IsSloppyModeFunction is always a bug, because the receiver would be wrapped in the wrong context. So the %IsSloppyModeFunction helper is gone now, and many of the buggy uses of %_CallFunction are also eliminated. If you ever need to call something with a different receiver, then %_Call is your friend now. It does what you want and implements the call sequence fully (and correct).

A LiveRange is identified by 2 integers: the vreg() of its TopLevel, which is the virtual register (operand) ID; and a relative_id(), which has no meaning in the program, but is valuable in debugging or tracing scenarios. This change ensures that relative_id is unique even in cases of splinter ranges and their children.

- Modify js2c to accept --js and --nojs, - modify mksnapshot to accept --startup_src (instead of a positional parameter, so that it can be omitted), - modify v8.gyp to use the above so that no target has multiple output dependencies, and - update GN to use the switches above. (I have not succeeded in fixing the GYP->make translator to properly map multi-output rules, so that they work as expected in all edge cases. This CL signals defeat on that front, and instead I rewrite the GYP file to avoid that situation in the first place.)
