When the regexp pattern parser encounters an unbound reference to a
capturing group, it needs to scan ahead to decide whether it really
is a reference. The scan advances to the end of the pattern string
and sets has_more_ to false, but fails to reset it to true so that
later on, parsing a character class wrongly fails.

Revert part of r14179. From the regression test's comment:
Currently, the gap resolver doesn't handle moves from a ConstantOperand to a
DoubleRegister, but these kind of moves appeared when HConstant::EmitAtUses
was changed to allow special double values (-0, NaN, hole). So we should
either enhance the gap resolver or make sure that such moves don't happen.

Fix worst-case behavior of MergeRemovableSimulates().
...
Currently, when a long series of removable simulates are merged, we do
this by merging them one by one as we find them. As we merge the value
value lists of the simulates, those lists snowball so that we get a
quadratic complexity wrt runtime and memory consumption.
Instead, we gather simulates that need to be merged, and merge them
backwards starting from the last simulate.

Make __proto__ a real JavaScript accessor property.

This turns the __proto__ callback from a foreign callback into a real
JavaScript accessor. It makes the accessor behavior of this property
explicit.
