Add additional DWARF 5 language constants.

[brucem]

Summary

This also hooks up the new C++14 language constant to be treated
the same as the other C++ language constants.

Fixing a typo.

looks good

Hey Greg,

I'd been mostly trying to avoid throwing all of the DWARF5 stuff in until
at least a preliminary version was released, but as long as everyone is OK
with the numbers possibly changing then I guess it's ok. I'd asked Bruce in
the clang side of the patch to hold off a bit.

Thoughts?

As you can see in this patch, the new language constants up to 0x0020 are already in LLDB. (I added them some months ago as I work on Dylan (among other things) and have started to do Dylan support in LLDB.)

[clayborg]

I would say to check them in and modify them when/if we need to. People need to start testing their DWARF5 functionality and LLD is a good way to start testing it. Maybe we should add a comment next to each language define:

// NOTE: DWARF5 constant, subject to change upon completion of the DWARF5 specification

Thoughts?

[echristo]

Sure. SGTM. I'll update the llvm side of things.
