Eddy (Eduard) Stefes 2a8e588c90 Add --print=backend-has-mnemonic and needs-asm-mnemonic directive ...

Add infrastructure to query LLVM backend for specific assembly mnemonics
and use it in compiletest to conditionally run tests based on instruction
availability.

This fixes test failures with naked-dead-code-elimination which requires
the `RET` mnemonic.
