<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Use "to" instead of "2" in internal names of conversion ops
Change the constructors for the primop union, and also names of the
literal conversion functions.
"2" runs into trouble when we need to do conversions from fixed-width
types, and end up with thing like "Int642Word".
Only the names internal to GHC are changed, as I don't want to worry
about breaking changes ATM.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Postpone associated tyfam default checks until after typechecking
Previously, associated type family defaults were validity-checked
during typechecking. Unfortunately, the error messages that these
checks produce run the risk of printing knot-tied type constructors,
which will cause GHC to diverge. In order to preserve the current
error message's descriptiveness, this patch postpones these validity
checks until after typechecking, which are now located in the new
function `GHC.Tc.Validity.checkValidAssocTyFamDeflt`.
Fixes #18648.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Remove GENERATED pragma, as it is not being used
@alanz pointed out on ghc-devs that the payload of this pragma does
not appear to be used anywhere.
I (@bgamari) did some digging and traced the pragma's addition back to
d386e0d2 (way back in 2006!).
It appears that it was intended to be used by code generators for use
in informing the code coveraging checker about generated code
provenance. When it was added it used the pragma's "payload" fields as
source location information to build an "ExternalBox". However, it
looks like this was dropped a year later in 55a5d8d9. At this point
it seems like the pragma serves no useful purpose.
Given that it also is not documented, I think we should remove it.
