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
