Summary:
log() is split into four functions:
- elog()/log()/vlog() have different severity levels, allowing filtering
- dlog() is a lazy macro which uses LLVM_DEBUG - it logs to the logger, but
conditionally based on -debug-only flag and is omitted in release builds
All logging functions use formatv-style format strings now, e.g:
log("Could not resolve URI {0}: {1}", URI, Result.takeError());
Existing log sites have been split between elog/log/vlog by best guess.
This includes a workaround for passing Error to formatv that can be
simplified when D49170 or similar lands.
