there isn't any Scanner class in there, just four CharacterStream classes.

Prototypes and their properties and methods are locked down to prevent fiddling with their operation, even if the build-in object leaks.

Made some built-in functions only work during bootstrapping.

The changes to scopes and parser introduce a VariableProxy
wrapping the function-name variable for function literals.
It seems the easiest way to get an AST id for the HSimulate
after context-slot stores in declarations.

We have to emit code for declarations later into the body block
(and not into the start block) so that the environment contains
the correct values.

In order to capture the environment effect of the declarations
that generate code (function declarations) I inserted a separate
AST id and a HSimulate after the declarations are visited.

Also fixes handling deopt in named function expressions:

Add nops to the branch-delay slots of the 'beq' and 'bne' instructions
used in the test-case. Having a branch instruction in the branch-delay-slot
of another branch is undefined on mips.

In regular code we avoid this by using the Branch() macro-instruction which
fills the branch-delay-slot with nop() automatically, unless the programmer
asks to use it (via USE_BRANCH_DELAY).

There is more info about branch-delay-slots on this page, and in the ISA
reference also on the page:
