[PATCH] lib: rename die_if_error to error_happened

["Jonathan Neuschäfer" <j.neuschaefer@gmx.net>]

The variable in question is set when an error message is output,
and doesn't control termination at all, so I think the new name
matches the semantics better.

Updated version: rebase on Xi's patch "sparse, llvm: die if error".
