This is the Blaze side of the support for emitting and using minimized bitcode files during the LTO indexing (thin link) step of a ThinLTO build. The llvm support has already been released to stable, and this needs to be submitted after the companion Crosstool support (unknown commit, will send for review once this larger part is reviewed).
This enables large applications successfully build using ThinLTO and -g, otherwise the bitcode files that are input to the LTO indexing step are huge and the maximum input size is exceeded.

This is a re-submission of commit 99de0d07574f808fee36826289cb1f5c83e3b3e0 (rolled back in commit eff8b365c172b7e904ac6f7bba0c893fed7c91a8) and a few tweaks: - The fix for the bug that caused the rollback (see line 888 in CppModel.java -- we now use addNonCodeInputs() instead of addObjectFiles() to pass in the processed header tokens)
- A few extra assertions
- A test case
- The re-submission of the parts of commit 603b540bbcd7414cd3e2c0b92c1c8985b035e41b that were also rolled back as collateral damage.
The bug report didn't contain a precise reproduction, but the bug is trivial enough that I'm comfortable with things this way.

*** Reason for rollback ***
Makes blaze unable to build //third_party/stl
IllegalArgumentException: complex.h.processed
at com.google.common.base.Preconditions.checkArgument(Preconditions.java:127)
at com.google.devtools.build.lib.util.Preconditions.checkArgument(Preconditions.java:38)
at com.google.devtools.build.lib.rules.cpp.CppLinkActionBuilder.addObjectFile(CppLinkActionBuilder.java:831)
NOT a clean rollback; conflict in one file (CppCompilationContext.java).
So this also partially rolls back commit 603b540bbcd7414cd3e2c0b92c1c8985b035e41b (just the change in that file).
*** Original change description ***
Cleanup: store non-code inputs to link actions separately.

for targets in the transitive closure of a target that is built.
Rollback of commit e01291a1a3d65cd706190c9bf0c8cfc585f38eb7.
Added an additional test to check that the configuration value is actually
effectively used.

for targets in the transitive closure of a target that is built.
Previously, this would only happen if a link action for the library containing
the headers was also built; this specifically means it did not trigger if
a library didn't contain source files, as there is no link action for such
libraries. That led to no header-only libraries would get their headers parsed,
which includes all cc_public_library rules.
Adding a flag to introduce this under so we can switch it on independently from
the blaze release. Once it is switched on, we can remove the edges in the
action graph from the link actions to the header processing actions.

This should make ThinLTO work with .o files that are not generated by
compiling C++ in a cc_library()

The headers were modified with
`find . -type f -exec 'sed' '-Ei' 's|Copyright 201([45]) Google|Copyright 201\1 The Bazel Authors|' '{}' ';'`
And manual edit for not Google owned copyright. Because of the nature of ijar, I did not modified the header of file owned by Alan Donovan.
The list of authors were extracted from the git log. It is missing older Google contributors that can be added on-demand.

This is renamed from the previous name emitCompileActionsIfEmpty, which was
a misnomer, because it didn't affect compile actions at all.
Update the callers to no longer call the method if not necessary, which leaves
only CcLibrary. CcBinary doesn't hit the link action code path, as it sets the
link type to either DYNAMIC_LIBRARY or EXECUTABLE.
This is in preparation for removing the implicit outputs from cc_library, which
should allow building header-only libraries on MacOS.
