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.

The driver crate is effectively the "main" function for the rust compiler. It orchestrates the compilation process and "knits together" the code from the other crates within rustc. This crate itself does not contain any of the "main logic" of the compiler (though it does have some code related to pretty printing or other minor compiler options).

For more information about how the driver works, see the rustc dev guide.
