1a64b02dcf harmony_scoping: Implement lexical bindings at top level 
This implements correct semantics for "extensible" top level lexical scope.
The entire lexical scope is represented at runtime by GlobalContextTable, reachable from native context and accumulating global contexts from every script loaded into the context.

When the new script starts executing, it does the following validation:
- checks the GlobalContextTable and global object (non-configurable own) properties against the set of declarations it introduces and reports potential conflicts.
- invalidates the conflicting PropertyCells on global object, so that any code depending on them will miss/deopt causing any contextual lookups to be reexecuted under the new bindings
- adds the lexical bindings it introduces to the GlobalContextTable

Loads and stores for contextual lookups are modified so that they check the GlobalContextTable before looking up properties on global object, thus implementing the shadowing of global object properties by lexical declarations.

2b026851ac Scanner: disallow unicode escapes in regexp flags. 
The spec explicitly forbids them. V8 never handled them properly either, just
the Scanner accepted them (it had code to add them literally to the
LiteralBuffer) and later on, Regexp constructor disallowed them.

According to the spec, unicode escapes in regexp flags should be an early error
("It is a Syntax Error if IdentifierPart contains a Unicode escape sequence.").

Note that Scanner is still more relaxed about regexp flags than the
spec. Especially, it accepts any identifier parts (not just a small set of
letters) and doesn't check for duplicates.

88efe28d3c [turbofan] Combine JSToNumber and ChangeTaggedToFloat64 for fast SMI case. 
This does the following optimization during ChangeLowering:

 ChangeTaggedToFloat64(JSToNumber(x)) =>
   if IsSmi(x) then ChangeSmiToFloat64(x)
   else let y = JSToNumber(x) in
     if IsSmi(y) then ChangeSmiToFloat64(y)
     else LoadHeapNumberValue(y)

Also cleanup/rearrange some code duplication in ChangeLowering.

9b72f14ced Turn ToNumberStub into a PlatformCodeStub again. 
The HydrogenCodeStub is too expensive and there's no easy way to reduce
this cost, so turning it into a PlatformCodeStub solves that problem
until we can use TurboFan for code stubs.
