[PATCH] D86406: Speedup llvm-dwarfdump 3.9x

[Joerg Sonnenberger via Phabricator via llvm-commits]

joerg added a comment.

Can you change `raw_fd_ostream::has_colors` to memoize the result of `FileDescriptorHasColors(FD)` instead? That should give most of the performance gain without breaking the abstractions as much.
