Original commit message:

    [riscv] Fix sp handling in MacroAssembler::LeaveFrame

    Keep sp <= fp to ensure that data right above fp doesn't get clobbered
    by an inopportune signal and its handler.

    Such clobbering can happen in e.g. Node.js when JIT-compiled code is
    interrupted by a SIGCHLD handler.

    Bug: None
