Don't rerun Mir passes when inlining

When inlining a function using the Mir inliner, we shouldn't rerun the
various Mir passes on it because the Mir has already been lowered and
that wil break various early Mir passes.

The issue in #50411 is that we've inlined a function with promotions
whose Mir has already been lowered. The promotions are then copied into
the local function and we begin to run passes on their lowered Mir
which causes the ICE.

Fixes #50411
