 testsuite: disable 'optllvm' for unregisterised compiler

 commit 74615f412ad3de2910a156ff494bfe5497fada7e
 ("UNREG: ignore -fllvm (Trac #13495)") enabled
 'optllvm' tests to be ran in 'make fulltest' mode.

 As a result many (~1000) tests fail due to stderr misamatch:
   +when making flags consistent: warning:
   +    Compiler unregisterised, so compiling via C

 The change removes 'optllvm' tests for unregisterised compiler.
