preposterously large for some lookup tables -- in C++ classes generated by
template instantiation, it's very common for the number of lookup results to be
either 1 or 2.
This reduces size of a libstdc++ module by 7-15%.

Profile readers using incompatible on-disk hash table format can now share the same
implementation and interfaces.

utils/sort_includes.py.
I clearly haven't done this in a while, so more changed than usual. This
even uncovered a missing include from the InstrProf library that I've
added. No functionality changed here, just mechanical cleanup of the
include order.

Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)
Changes made by clang-tidy with minor tweaks.

OnDiskHashTable::insert() calls the Item constructor via placement new, but
nothing called the destructor. This matters in cases when the Info template
parameter has key_type or data_type typedefs that have a destructor, for
example like IdentifierIndexWriterTrait in clang's GlobalModuleIndex.cpp.
This fixes a 5-year old bug that's been around since the OnDiskHashTable code
was added in r64192. Bug found by LSan!

This changes the on-disk hash to get the type to use for offsets from
the Info type, so that clients can be more flexible with the size of
table they support.

This changes the on-disk hash to get the size of a hash value from the
Info type, so that clients can be more flexible with the types of hash
they use.

This introduces clang's Basic/OnDiskHashTable.h into llvm as
Support/OnDiskHashTable.h. I've taken the opportunity to add doxygen
comments and run the file through clang-format, but other than the
namespace changing from clang:: to llvm:: the API is identical.
