Closes #20532. This implements CLC proposal 104:
https://github.com/haskell/core-libraries-committee/issues/104
The design is explained in Note [DataToTag overview]
in GHC.Tc.Instance.Class. This replaces the existing
`dataToTag#` primop.
These metric changes are not "real"; they represent Unique-related
flukes triggering on a different set of jobs than they did previously.
See also #19414.

An Anchor has a location and an operation, which is either that it is
unchanged or that it has moved with a DeltaPos
data Anchor = Anchor { anchor :: RealSrcSpan
, anchor_op :: AnchorOperation }
An EpaLocation also has either a location or a DeltaPos
data EpaLocation = EpaSpan !RealSrcSpan !(Strict.Maybe BufSpan)
| EpaDelta !DeltaPos ![LEpaComment]
Now that we do not care about always having a location in the anchor,
we remove Anchor and replace it with EpaLocation
We do this with a type alias initially, to ease the transition.
The alias will be removed in time.
We also have helpers to reconstruct the AnchorOperation from an
EpaLocation. This is also temporary.

...mostly so that 16d6b7e835ffdcf9b894e79f933dd52348dedd0c
which reworks unaligned writes in Builder can see wider testing.
The less-terrible code for unaligned writes used in Builder on
hosts not known to be ulaigned-friendly also takes less effort
for GHC to compile, resulting in a metric decrease for T21839c
on some platforms.
The metric increase on T21839r is caused by the unrelated commit
750dac33465e7b59100698a330b44de7049a345c. It perhaps warrants
further analysis and discussion (see #23822) but is not critical.
