The current implementation of classes throws the TypeError at the wrong
point, after activating a new context when directly calling a class
constructor. According to the spec, the TypeError has to be thrown
in the caller context.

The callees are expected to properly set the number of actual
arguments passed to the callee, which is now represented correctly
in the TurboFan graphs by a new Parameter right before the context
Parameter.  Currently this is only being used for outgoing calls.

Note that this requires disabling two of the TF code stub tests,
because of the JavaScript graphs are not automagically compatible
with abitrary (incoming) code stub interface descriptors.  If we
want to support JS code stubs at all, then we need to find a sane
way to feed in this information.

Drive-by-fix: Don't insert a direct call to a classConstructor.

This removes special casing for the 'f.arguments' property accessor. Any
local 'arguments' variable should not be allowed to influence the value
returned by the indirect 'f.arguments' property. That property creates a
new object with a separate identity everytime it is read. This is by now
consistent with other browsers.

We don't need to distinguish between signed and unsigned integral
representations in the big boy type system. It actually even hurts
in some cases. The representation is only about the way the values
are mapped to bits in memory/registers, but the interpretation of
the bits is specified by the semantic dimension.

We used to mark a block as needing frame based solely on
the spill list. With splintering, that is not entirely
accurate. With this change, for ranges that spill only in
deferred blocks, we mark the start of each block in which a
child range spills as needing a frame.

several releases now, and were only separate originally to enable
loading them via a runtime flag. This patch simply merges them into
the main implementation files for Arrays and TypedArrays, respectively.

This matches the approach used for @@isConcatSpreadable, and seems to
match what Mozilla is planning to do in Firefox.

Given that there's already little compatibility around cross-origin toString
results, there seems to be little hazard in making this change even before
spec language hits the HTML spec.
