Exclude specialized test suites from `check-all`. Without that, FileCheck and TableGen tests are run twice, and then those that use `%t` seem to fail

```
FAIL: LLVM :: TableGen/RuntimeLibcallEmitter-conflict-warning.td (70661 of 87819)
******************** TEST 'LLVM :: TableGen/RuntimeLibcallEmitter-conflict-warning.td' FAILED ********************
Exit Code: 2
********************
PASS: LLVM :: TableGen/RuntimeLibcallEmitter-conflict-warning.td (70665 of 87819
```

Note: Same test with 2 different numbers, so its run twice and when that happens concurrently, the %t file is shared among the 2 instances causing bad interaction and test failure.
