Unfortunately, the fix I picked up in #127 seems to have some additional dependency that is not present on the 13.x branch. It works for a truncating store to i32 and i16, but not i8. There's some issue related to 8-bit FPR subreg copies.
This reverts that commit, and instead applies the workaround fix that was committed before the "proper" fix landed. This one works for both i32 and i8 truncating stores, at least based on a reduced test case.
