  * Use the PackageDbStack in the local build info and compiler modules
  This lets us pass a whole stack of package databases to the compiler.
  This is more flexible than passing just one and working out what
  other dbs that implies. This also lets us us more than one specific
  package db, which we need for the inplace package db use case.

    M ./Distribution/Simple/Compiler.hs +8
    M ./Distribution/Simple/Configure.hs -11 +12
    M ./Distribution/Simple/GHC.hs -8 +13
    M ./Distribution/Simple/LHC.hs -8 +13
    M ./Distribution/Simple/LocalBuildInfo.hs -2 +2
    M ./Distribution/Simple/Register.hs -3 +6
