Summary:
This change moves tests for checkers and infrastructure into separate
directories, making it easier to find infrastructure tests. Tests for
checkers are already easy to find because they are named after the
checker. Tests for infrastructure were difficult to find because they
were outnumbered by tests for checkers. Now they are in a separate
directory.

Summary:
Continuation of D46504.
Example output:
```
$ clang-tidy -enable-check-profile -store-check-profile=. -checks=-*,readability-function-size source.cpp
$ # Note that there won't be timings table printed to the console.
$ cat *.json
{
"file": "/path/to/source.cpp",
"timestamp": "2018-05-16 16:13:18.717446360",
"profile": {
"time.clang-tidy.readability-function-size.wall": 1.0421266555786133e+00,
"time.clang-tidy.readability-function-size.user": 9.2088400000005421e-01,
"time.clang-tidy.readability-function-size.sys": 1.2418899999999974e-01
}
}
```
There are two arguments that control profile storage:
* `-store-check-profile=<prefix>`
By default reports are printed in tabulated format to stderr. When this option
is passed, these per-TU profiles are instead stored as JSON.
If the prefix is not an absolute path, it is considered to be relative to the
directory from where you have run :program:`clang-tidy`. All `.` and `..`
patterns in the path are collapsed, and symlinks are resolved.
Example:
Let's suppose you have a source file named `example.cpp`, located in
`/source` directory.
* If you specify `-store-check-profile=/tmp`, then the profile will be saved
to `/tmp/<timestamp>-example.cpp.json`
* If you run :program:`clang-tidy` from within `/foo` directory, and specify
`-store-check-profile=.`, then the profile will still be saved to
`/foo/<timestamp>-example.cpp.json`

Summary:
As discussed in D45931, currently, profiling output of clang-tidy is somewhat not great.
It outputs one profile at the end of the execution, and that profile contains the data
from the last TU that was processed. So if the tool run on multiple TU's, the data is
not accumulated, it is simply discarded.
It would be nice to improve this.
This differential is the first step - make this profiling info per-TU,
and output it after the tool has finished processing each TU.
In particular, when `ClangTidyASTConsumer` destructor runs.
Next step will be to add a CSV (JSON?) printer to store said profiles under user-specified directory prefix.
