X87: [crankshaft] Record inlined shared function infos instead of closures.

X87: [crankshaft] Record inlined shared function infos instead of closures.

port 388e791df91c299507d62f91bc4f618a4dc80276 (r28672).

original commit message:

   The list of inlined functions is used in exactly two places - for live
    edit and to prevent code flushing for inlined functions - and those are
    fine with SharedFunctionInfo and don't require a closure.

    This is one additional step towards inlining based on SharedFunctionInfo
    instead of JSFunction.
