Fix run-pass tests when CARGO_TARGET_DIR is not set
r? @lzutao
I got
```
thread '[ui] ui/crashes/ice-1969.rs' panicked at 'failed to exec `"target/debug/test_build_base/crashes/ice-1969.stage-id"`: Os { code: 2, kind: NotFound, message: "No such file or directory" }', /home/pkrones/.cargo/registry/src/github.com-1ecc6299db9ec823/compiletest_rs-0.4.0/src/runtest.rs:1350:25
```
on tests with `// run-pass` locally. The reason for this is, that I haven't set `CARGO_TARGET_DIR` and then `"target"` was used as the `CARGO_TARGET_DIR`. It seems, that `compiletest-rs` cannot deal with relative paths for `// run-pass` tests.

Fix error E0460 when compiled on Rustc repo
Sadly, this mostly reverts #5121. Now I use HashMap to only store one rlib
per crate. But that would not work when non-compatible version of the same crate show up.

Make it possible to correctly indent snippet_block snippets
This adds a `indent_relative_to` arg to the `{snippet,expr}_block` functions. This makes it possible to keep the correct indentation of block like suggestions.
In addition, this makes the `trim_multiline` function private and adds a `indent_of` function, to get the indentation of the first line of a span.
The suggestion of `needless_continue` cannot be made auto applicable, since it would be also necessary to remove code following the linted expression. (Well, maybe it is possible, but I don't know how to do it. Expanding the suggestion span to the last expression, that should be removed didn't work)
changelog: Improve suggestions, when blocks of code are involved
Port mitsuhiko's excessive bools lints
Closes#4 .
changelog: add `struct_excessive_bools` and `fn_params_excessive_bools` lints.
I moved is_trait_impl_item check because at first I implemented it as a late pass for some reason but then I realized it's actually an early lint. But it's a useful function to have, should I move it into a separate pr?
Do not lint `unnecessary_unwrap` in external macros
Fixes#5131
I think we shouldn't lint `{panicking, unnecessary}_unwrap` in macros, not just `assert!`.
changelog: Fix false positive in `unnecessary_unwrap`
Improve compile_test and dogfood tests
* Hopefully this finally resolves the "multiple matching crates" error, e.g. #4015
* This handle some convenient CARGO env like CARGO_TARGET_DIR and CARGO_BUILD_TARGET

Prevent failing to restart setup-toolchain
If `rustup-toolchain-install-master` fails to install master
toolchain (in case `rustup update` executes at the same remove the
tmp directory), `cargo search` (which use master toolchain after
`rustup override` command) will fail. This leads to setup-toolchain
fails too.
