We have to emit code for declarations later into the body block

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:

07c1c9ebc7 MIPS: small test-case fix for chaining of fixup position. 
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:

458cdd6d8b Add a dependency of v8_base on WinSocket2 Windows library. 
v8_base depends on ws2_32.lib for accept() and some of the
other socket used for the debugger.

c6e42e1bfa Fix initial prototype of WeakMap function. 
The bootstrapper accidentally overwrote the constructor property of the Object
prototype because it used initial_object_prototype() as prototype for WeakMap.
Unfortunately this is not possible for experimental natives because they are
installed after the snapshot initialization finished.
