Inline scripts share the same URL, so lookup of script by URL on them
can give the wrong result. Also, their source positions are relative to
the start of the HTML file, so we need to infer the starting line from
the Script's compilation event.

As a drive-by, fix the tooltip to lock in-place on click.

This CL optimizes Heap::EnsureSweepingCompleted() by only ensure that
sweeping is finished for that object's page only and not for the whole
heap.

For this purpose the page is removed from the sweeping_list_ and
processed on the main thread. In case the object is in new space,
this method will just use EnsureIterabilityCompleted() since
the iterability task doesn't currently have any kind of synchronization.
Also the new space will generally be much smaller.

TNode has a templated constructor from TNode<U>, but this doesn't take
precedence over the auto-generated copy constructor, which results in a
warning being fired.  Fix by adding an explicit copy constructor that
does what the templated constructor does, which in turn requires fixing
some missing #includes that slipped by due to the lack of
LazyTemplateChecks() in the autogenerated copy constructor.

M1 hardware uses the CodeSpaceWriteScope (which uses MAP_JIT under the
hood), hence all other memory protection mechanisms should be disabled
there.
Trying to protect code space allocated with MAP_JIT would fail
otherwise, resulting in a CHECK failure.

removes these lines.

This moves all of the FunctionTemplateInfo code into templates.cc and
removes the inline keyword from BreakAtEntry which is moved out of
templates-inl.h. As a result templates-inl.h no longer depends on
shared-function-info-inl.h. This in turn uncovered lots of other missing
includes which are now in place.
