Fixes #25529.

Unfortunately, `tryM` doesn't catch module lookup errors. This manifests as a failure to build ghc-prim in `--make` mode on the GHC 9.10 branch. Instead, we explicitly avoid doing lookups when we are compiling ghc-prim or ghc-internal instead of relying on catching the exception. - - - - - ce5f1782 by Zubin Duggal at 2025-07-24T23:53:13+05:30 Consider `PromotedDataCon` in `tyConStupidTheta` Haddock checks data declarations for the stupid theta so as not to pretty-print them as empty contexts. Type data declarations end up as `PromotedDataCon`s by the time Haddock performs this check, causing a panic. This commit extends `tyConStupidTheta` so that it returns an empty list for `PromotedDataCon`s. This decision was guided by the fact that type data declarations never have data type contexts (see (R1) in Note [Type data declarations]). Fixes #25739.

Any consecutive lines with birdtracks will only have initial whitespace stripped up to the column of the first line.

We also need to look in the modules on which they depend, including those outside of this package. Fixes #25147. Fixes #26079.
