[ELF] Add a NOP instruction to make LLVM generate a mapping symbol 

This is a test change applicable for ARM targets.

Previously LLVM would generate a mapping symbol when code contains only

and to be more close to the ARM ELF ABI.

The test case is changed to check for behavior with minimal changes.
