X87: [es6] Make new.target work in functions.

X87: [es6] Make new.target work in functions.

port 7a63bf77eb7610afdc1a968f7660781e5160ba8d (r29358).

original commit message:

    This makes new.target work in [[Call]] and [[Construct]] of ordinary
    functions.

    We achieve this by introducing a new construct stub for functions that
    uses the new.target variable. The construct stub pushes the original
    constructor just above the receiver in the construct frame.
