    x86: Restore the frame pointer in word_mode

    We must restore the frame pointer in word_mode for eh_return epilogues
    since the upper 32 bits of RBP register can have any values.

    Tested on Linux/x32 and Linux/x86-64.

            Backport from master

            pointer in word_mode for eh_return epilogues.
