Change Option<Value> to Value, using ByVal(Undef).
...
This job isn't quite finished because it caused me to discover bugs
related to reading `ByVal(Undef)` when a `ByValPair` is expected, e.g.
for a fat pointer. This wasn't a problem with the `None` of
`Option<Value>`, but I realized an equivalent bug existed even then,
since you could transmute a `u64` like `ByVal(Bytes(42))` to a fat
pointer type on 32-bit targets.
Likewise, you could transmute a fat pointer to `u64` and get panics
related to expecting `ByVal` but finding `ByValPair`, so the problem
goes both ways.

Stop before trans so I can test non-x86_64 targets.
...
I had problems when it tried to link outputs for targets other than my
host.
This re-breaks tests with auxiliary builds. I'm not sure what to do
about those right now.

Turn PrimVal into an enum including Undefined.
...
This is step 1 of a refactoring to fix #95 . The `Undefined` variant is
so far unused and the old `bits` and `relocation` fields are emulated
with two new temporary methods. There should be no functional change due
to this commit.
