Porting mistake in ccbb4ff0 '[builtins] Unify the various versions of [[Call]]
with a Call builtin.', which only showed as debug assertion in later commit
db2ba190 '[runtime] Replace many buggy uses of %_CallFunction with %_Call.'

- 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.)

This removes the DisallowAllocationFailure assertion scope which mostly
coincided with the AlwaysAllocateScope anyways. Access to the bitfield
in the Isolate was not synchronized and hence the AlwaysAllocateScope
was not thread-safe in debug mode, now it is.

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).

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%.

    result objects from JavaScript builtins (there's a matching factory
    method for C++ code).

port fbad6366 (r30467)

original commit message:

    The call protocol requires that the register dedicated to the number of
    actual arguments (i.e. rax on x64) always contains the actual arguments.
    That means after adapting arguments it should match the number of
    expected arguments.  But currently we pass some semi-random value
    (usually some stack address) after adapting arguments.

    It looks like this is currently not observable anywhere, because our
    builtins and functions either don't look at the number of arguments and
    just make hard coded (unchecked) assumptions, or are marked as "don't
    adapt arguments", which bypasses the broken code in the trampoline for
    arguments adaption.  Nevertheless this should be fixed.
