Currently we lower shifts directly to machine operators, and add an
appropriate Word32And to implement the & 0x1F operation on the right
hand side required by the specification. However for Word32And we assume
Int32 in simplified lowering, which is basically changes the right hand
side bit interpretation for the shifts from Uint32 to Int32, which is
obviously wrong. So now we represent that explicitly by proper
simplified operators for the shifts, which are lowered to machine in
simplified lowering.

The only right way to enable access checks is to install access check callbacks on an object template via v8::ObjectTemplate::SetAccessCheckCallbacks(). It does not make sense to enable access checks on an arbitrary object.

Clang warns if there are missing braces around a subobject
initializer. The most common idiom that triggers this is:
  STRUCT s = {0};
if the first field of STRUCT is itself a struct. This can
be more simply written as:
  STRUCT s = {};
which also prevents the warning from firing.

port 7015fd20 (r29402)

original commit message:

    Up until now the context register was listed explicitly in each stub's
    CallInterfaceDescriptor. This was problematic, because it was listed
    first in the list of register parameters--which is fine for Crankshaft,
    which is more or less built to handle the context as the first
    parameter-- but not ideal for TurboFan, which adds the context at
    the end of all function parameters. Now the context register is no
    longer in the register list and can be handled appropriately by both
    compilers. Specifically, this allows the FunctionType specified for
    each CallInterfaceDescriptor to exactly match the parameter register
    list.
