When an AST file is built based on another AST file, it can use a decl from
the fist file, and therefore mark the "isUsed" bit. We need to note this in
the AST file so that the bit is set correctly when the second AST file is
loaded.
This patch introduces the distinction between setIsUsed() and markUsed() so
that we don't call into the ASTMutationListener callback when it wouldn't
be appropriate.
Fixes PR16635.

uncovered.
This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

In the included testcase, soma thinks that we already have a definition after we
see the out of line decl. Codegen puts it in a deferred list, to be output if
a use is seen. This would break when we saw an explicit template instantiation
definition, since codegen would not be notified.
This patch adds a method to the consumer interface so that soma can notify
codegen that this decl is now required.

-Use an array of offsets for all preprocessed entities
-Get rid of the separate array of offsets for just macro definitions;
for references to macro definitions use an index inside the preprocessed
entities array.
-Deserialize each preprocessed entity lazily, at first request; not in bulk.
Paves the way for binary searching of preprocessed entities that will offer
efficiency and will simplify things on the libclang side a lot.
