compiler-rt: Rename .cc file in lib/sanitizer_common to .cpp

2019-07-31T18:51:27+00:00

See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran

  for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $f . ; done

and manually updated (many) references to renamed files found by that.

[fuzzer] Use RawPrint instead of Printf for instrumentation warning

2019-01-31T20:32:20+00:00

Summary:
Use RawPrint instead of Printf for instrumentation warning because
Printf doesn't work on Win when instrumentation is being
initialized (since OutputFile is not yet initialized).
