This breaks backwards compatibility of IR. _If_ you want to go ahead with this
patch (which is fundamentally just a change to the internal representation of
features) then I would suggest breaking backwards compatibility by having
`target-feature="+mte"` mean FEAT_MTE and `target-feature="+mte2"` mean
FEAT_MTE2. Then if anyone happens to be using MTE2 instructions in inline
assembly with `target-feature="+mte"` they will get an error, but for the vast
majority of cases, the change from FEAT_MTE2 to FEAT_MTE for
`target-feature="+mte"` will have no effect.
