    Hadrian: Add support for building stage3 · 6486c6e4
    Matthew Pickering authored
    This ticket enables the building of a `stage3` compiler by making the
    build logic more consistent and predictable in Hadrian.
    Two of the main changes are:
    1. In order to build anything at stageN we use the package database
    present at stageN. Fixing #16069
    2. `haddock` and `ghc-tags` are built
    as stage1 executables (with the stage1 compiler) rather than as
    stage2 compiler. Fixing
    In order to build a stage3 compiler, you have to set the new `finalStage` hadrian option to `Stage3`.
