X87: [stubs] Don't pass name to Load/StoreGlobalViaContext stubs.

X87: [stubs] Don't pass name to Load/StoreGlobalViaContext stubs.

port 5dff4bdff06c0463db1e876af7541af2b715392c (r29886).

original commit message:

    No need to pass the name explicitly to the stubs; the runtime can
    extract the name from the ScopeInfo (the extension of the
    ScriptContext) on-demand easily without any performance impact.
