Allow user languages in `dwarf::isCPlusPlus`

When the source language is not one of the DW_LANG_*, dwarf::isCPlusPlus fails
with a call to  llvm_unreachable. However, any language between DW_LANG_lo_user
and DW_LANG_hi_user should be accepted.

This is causing errors on some environments for Crystal language:

I'm sending the patch with a possible solution.
