[lldb/Interpreter] Fix language detection for the REPL InitFile

Authored by mib on Sep 3 2020, 1:31 AM.



Previously, before loading the REPL language-specific init file, lldb
checked the selected target language in which case it returned an unknown
language type with the REPL target.

Instead, the patch calls Language::GetLanguagesSupportingREPLs and
look for the first element of that set. In case lldb was not configured
with a REPL language, then, it will just stop sourcing the REPL init
file and fallback to the original logic (continuing with the default
init file).

This patch sparks joy, but the fact that this all is dead code without Swift doesn't spark joy. But as it's up to me to revive this code and the downstream Swift test looks fine, I'll sign this off. Thanks!


This could now be else return to make the error control flow a bit clearer.


= eLanguageTypeUnknown? I don't think we usually initialise enums with braces and it makes the default value clearer.
