Eelco Dolstra fb7d315411 Merge pull request #10570 from layus/shared_caches 
Share evaluation caches across installables

Before:

$ rm -rf ~/.cache/nix && time -f '%E' nix build --dry-run \
  'nixpkgs#hello' \
  'nixpkgs#clang' \
  'nixpkgs#cargo' \
  'nixpkgs#rustup' \
  'nixpkgs#bear' \
  'nixpkgs#firefox' \
  'nixpkgs#git-revise' \
  'nixpkgs#hyperfine' \
  'nixpkgs#curlie' \
  'nixpkgs#xz' \
  'nixpkgs#ripgrep'
0:03.61

After:

$ rm -rf ~/.cache/nix && time -f '%E' nix build --dry-run \
  'nixpkgs#hello' \
  'nixpkgs#clang' \
  'nixpkgs#cargo' \
  'nixpkgs#rustup' \
  'nixpkgs#bear' \
  'nixpkgs#firefox' \
  'nixpkgs#git-revise' \
  'nixpkgs#hyperfine' \
  'nixpkgs#curlie' \
  'nixpkgs#xz' \
  'nixpkgs#ripgrep'

This could probably use a more proper benchmark...

Fixes #313
