also be inefficient. Leaving Result in a valid state, which might be a

Bug 1661428 - Use CompactPair instead of Variant for trivially default-constructible V and UnusedZero E. r=froydnj
...
It seems that the clang toolchain has trouble optimizing away the tag access in
a `mozilla::Variant`. Use of a `CompactPair` seems to be better when `E` is
small (all cases where `UnusedZero<E>` is true are small right now anyway).
While this doesn't change `sizeof(Result<V, E>)` in most cases, it makes
the generated code simpler/smaller: As of now, this reduce the overall VM size
of libxul.so by ca. 59K.
Without additional effort, this requires and leads to default-construction of
a `V` even in cases where it is never accessed, so this is restricted to
trivially default-constructible `V` for now.
This could be avoided by replacing `CompactPair<V, E>` by
`CompactPair<AlignedStorage2<V>, E>`.
