<pre>After building some llvm tools with -fcoverage-mapping
-fprofile-instr-generate, running the tools, and merging the resulting raw
profiles, there are "N functions have mismatched data" warnings.
Investigate the source of these warnings, and improve the diagnostic to be more
helpful/precise.</pre>
