Subject: [PATCH 03/13] return dummy cc and friends during dry runs

Some targets are added to these hashmaps at runtime, and are not present
during dry runs. To avoid errors, this commit changes all the related
functions to always return empty strings/paths during dry runs.

Subject: [PATCH 07/13] make sure the standard library compiles properly with
 synthetic targets

It might happen that a synthetic target name does not match one of the
hardcoded ones in std's build script, causing std to fail to build. This
commit changes the std build script avoid including the restricted-std
feature unconditionally when a synthetic target is being built.

Subject: [PATCH 10/13] bless mir-opt

To reproduce the changes in this commit locally:

- Run `./x test tidy` and remove all the output files not associated
  with a test file anymore, as reported by tidy.
- Run `./x test tests/mir-opt --bless` to generate the new outputs.
