[pushed 0/7] diagnostics: remove "tree" dependency from diagnostic paths

[David Malcolm <dmalcolm@redhat.com>]

This patch kit removes the dependency on "tree" from diagnostic paths,
renaming tree-diagnostic-path.cc to diagnostic-path.cc.

I have an updated prototype of libdiagnostics that uses this to support
execution paths.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Successful run of analyzer integration tests on x86_64-pc-linux-gnu.
Pushed to trunk as r15-1410-gf89f9c7ae7190c through
r15-1416-g524cdf4dab610e.
