[PATCH] Use CommonOptionsParser in clang-query. This fixes its support of the fixedcompilation database and makes it behave consistently with other clang tools.

[Peter Collingbourne]

LGTM

I based this code on tool-template, so I was unaware of the existence of CommonOptionsParser. Perhaps it would be a good idea to update tool-template as well?
