Backport c0b3e49

We encountered this problem in Zig, causing all of our
`mips(el)-linux-gnueabi*` tests to fail:
ziglang/zig#21215

For these unusual cases, let's just bail in `MipsFastISel` since
`MipsTargetLowering` can handle them fine.

Note: I don't have commit access.

Fine by me, but I was under the impression that there won't be any more 19.x releases?

That is the case so far.
