The use-def relation between phis is mainly "forwards" (i.e. from phis with
smaller IDs to ones with larger IDs), so the fixed point computation terminates
faster when iterate through the phis in a "backwards" manner. This is quite
visible in complex Mandreel-generated code, where a few hundred phis with
non-trivial use-def chains are generated.

There is an optional parameter to the function, with default value being a null handle. We then check that this is a flat string.

This is so we can ignore libv8_g.so and libv8preparser_g.so when running git status.

TEST=git status. You should not see the above libraries in the output.

Duplicate identifier detection must be an early syntax error in strict code,
so errors in otherwise lazily compiled functions must be caught in the
preparser.

Originally introduced in r8541 and reverted in r8542.

The prototype of builtin functions is already unwritable, so we don't
have to make it so (the default map for functions changes after builtins
are initialized).

We no longer need to make the prototype non-extensible, since all properties
that are ever read by the bultins code has been added and frozen already.
Adding properties to the prototype, or changing its __proto__, cannot affect
code.

Removing these two pieces of initialization code reduces the snapshot size
by a few Kb.

When with or catch is nested inside finally, we were not properly restoring
the context in the stack for the finally code.  Also, as a small
optimization, restore it from the handler block instead of iteratively
unwinding contexts.

'Let's inside a 'with' would initialize the variable
using the StoreContextSlot runtime function which
would fail because it checks that the variable does
not hold the hole value.

ConvertDescriptorToField on the callback on each and every native
