x86: allow "=rm" in native_save_fl()
This is a partial revert of f1f029c7bfbf4ee1918b90a431ab823bed812504.
"=rm" is allowed in this context, because "pop" is explicitly defined
to adjust the stack pointer *before* it evaluates its effective
address, if it has one. Thus, we do end up writing to the correct
address even if we use an on-stack memory argument.
The original reporter for f1f029c7bfbf4ee1918b90a431ab823bed812504 was
apparently using a broken x86 simulator.
