Automated g4 rollback of commit 38b835097f9ae9a6062172b8a33ec2e2d1edde20.

*** Reason for rollback ***

Breaking Bazel build on linux, see http://ci.bazel.io/job/bazel-tests/733/

Repro: bazel build //src/test/java/com/google/devtools/build/lib:packages_test

Found by bisecting.

*** Original change description ***

Only allocate some formerly frequently allocated PathFragment objects once.

This reduces both gc churn and retained memory usage.
