As a data point: I ran -Wshadow on our code base with a similar, but simpler
patch (http://reviews.llvm.org/D18395, just disables the warning on ctor
parameters named after fields). It removes more than half of the hits (from
~100k initially) and a random sample of ~100 removed removed hits didn't
contain any issues that we'd like to still be warning about.
Ultimately, I think, this diagnostic should be made much less noisy to be
actually useful. So maybe even starting with a removal of a larger subset of
warnings (and then gradually adding back the cases that seem to be important to
flag) would be better.
