Rather than rolling our own functions to read little endian data
from a buffer, we can use the support in llvm's Endian.h.
No functional change.

Unfortunately, this is not as simple as it was implemented previously, and
actually requires doing a merge sort.

force the lookup table for the decl context to be built, import a module that
adds more decls for the name, then write out our module without looking up the
name.

specializations in PCHs if they're instantiated eagerly, because they're
constexpr or have a deduced return type.)

and expressions. No functionality change (but the generated PCM files are
incompatible with earlier versions of Clang).

What's going on in the test case (without the patch applied) is this:
When the header is parsed, decltype(B()) is canonicalized to decltype(Y()),
because that was the first parsed equivalent decltype expression. Hence, the
TemplateSpecializationType for Id<decltype(B())> ends up with
SubstTemplateTypeParmType(T, decltype(Y())) as the AliasedType member.
When the PCH file is included and the AST reader reads Id<decltype(B())>, it
sees decltype(B()) before decltype(Y()). So, this time decltype(B()) ends up
being the canonical type for both decltypes, which leads to an assert violation
when the reader calls getSubstTemplateTypeParmType with the non-canonical
decltype(Y()) as the replacement type.

This is because the PCH is tied to the module files, if one of the module files changes or gets removed
the build system should re-build the PCH file.

Drive-by fixing some incorrect types where a for loop would be improperly using ObjCInterfaceDecl::protocol_iterator. No functional changes in these cases.

When building an AST file, we don't want to output HeaderFileInfo
structures for files that are not actually used as headers in the
current context. This can lead to assuming that unrelated files have
include counts of 0, defeating multiple-include prevention.
This is accomplished by adding an IsValid bit to the HFI.
