This commit passes -j to hadrian in the hadrian/hie-bios scripts. When
the user starts HLS in a fresh clone that has just been configured, it
takes quite a while for hie-bios to pick up the ghc flags and start
actual indexing, due to the fact that the hadrian build step defaulted
to -j1, so -j speeds things up and improve HLS user experience in GHC.
Also add -j flag to .ghcid to speed up ghcid, and sets the Windows
build root to .hie-bios which also works and unifies with other
platforms, the previous build root _hie-bios was missing from
.gitignore anyway.

Convert hadrian buildscripts to unsuffixed, dashed form

final cleanups

Sebastian Graf authored 5 years ago and Marge Bot committed 5 years ago

By not building anything in the dynamic way on Windows, where we don't
have a working story for DLLs yet.

Also the ghcid command needs to call bash on the hadrian/ghci.sh script
explicitly as the path gets interpreted differently otherwise.

Add scripts and .ghci files for loading GHC into GHCi

Major credit to Csongor Kiss who wrote nearly all of settings.ghci

Some small modifications to GHC are needed to make this work, and this
diff depends on [D4986](https://phabricator.haskell.org/D4986) being
merged.

Test Plan:
Manual for now. I have some thoughts on how to run the entire testsuite
against
GHC-in-GHCi.
