CcToolchainProvider
As --fdo_optimize can point to a label, the path to the fdo profile can not be reliably determined in CppConfiguration.
In order to enable the fdo features (which depend on the path to the fdo profile), the logic from CppConfiguration.configurationEnabledFeatures() has been moved to CcCommon.configureFeatures(). The latter method has access to the fdo profile path through CcToolchainProvider.
RELNOTES: None.

This change is a follow-up to a recent change which allowed LLVM raw profile files
to be directly used with blaze. This change allows zipped LLVM raw profile
files.
This uses //tools/zip:zipper to extract the zipped file contents.
This also adds a new option to //tools/zip:zipper, 'j', to junk directories while
unzipping.
Tested:
blaze test //devtools/blaze/integration:fdo_test
blaze test //third_party/ijar/test:zip_test
RELNOTES[NEW]: Zipped LLVM profiles are now supported.

wrapper objects: for OwnedArtifacts, which are the most numerous during builds, and for Labels for TransitiveTraversalValues, which are the most numerous during queries.

SkyFunction.
This removes one of the two reasons for the existence of BuildConfiguration#prepareToBuild() which makes implementing dynamic configurations impossible and also makes FDO support halfway sane; now FDO is exactly as ugly as remote repositories, that is to say, reasonably okay.
Ideally, we'd implement the zip extraction as an Action and make it a TreeArtifact, but support for TreeArtifacts is not mature yet enough, so it's not possible at the moment.
