[PATCH] D27375: Let ubsan search UBSAN_SYMBOLIZER_PATH for llvm-symbolizer

I can imagine a separate environment variable being more convenient in some cases. I don't think we should deprecate it. Also, printing stuff can break user programs, so it should not be done by default, and doing it only with verbosity=1 is almost useless, no one will see it.

I'd add LLVM_SYMBOLIZER_PATH, maybe add UBSAN_SYMBOLIZER_PATH (just for consistency), and change the docs to point to LLVM_SYMBOLIZER_PATH and external_symbolizer_path.
