[llvm-profdata] Improve error messaging when merging mismatched profile data
Summary:
This change tries to make the root cause of instrumented profile data merge failures clearer.
Previous:
$ llvm-profdata merge test_0.profraw test_1.profraw -o test_merged.profdata
test_1.profraw: foo: Function count mismatch
test_1.profraw: bar: Function count mismatch
test_1.profraw: baz: Function count mismatch
...
Changed:
$ llvm-profdata merge test_0.profraw test_1.profraw -o test_merged.profdata
test_1.profraw: foo: Function basic block count change detected (counter mismatch)
Make sure that all profile data to be merged is generated from the same binary.
test_1.profraw: bar: Function basic block count change detected (counter mismatch)
test_1.profraw: baz: Function basic block count change detected (counter mismatch)
