value numbers to be assigned when calculating any particular value number.
Enhance the logic that detects new value numbers to take this into account,
for a tiny compile time speedup.  Fix a comment typo while there.

%cmp (eg: A==B) we already replace %cmp with "true" under the true edge, and
with "false" under the false edge.  This change enhances this to replace the
negated compare (A!=B) with "false" under the true edge and "true" under the
false edge.  Reported to improve perlbench results by 1%.

Remove HexagonGenIntrinsics.inc from Hexagon cmake file. It does not appear in the Makefile and the output it produces isn't used. The Hexagon intrinsics are all in the global Intrinsics.gen.

If the assignment operator is a scalar type, we continue to incorrectly reject
the initializer, but semantic analysis (and codegen) is correct for overloaded
operators.

There's more potential here, but these Exprs aren't used that often so I don't feel like doing heroic bit packing right now.

Apply the inheritance-padding trick to FloatingLiteral.
Shrinks CharacterLiteral from 32 to 24 bytes and the other two from 40 to 32 bytes (x86_64).

Inheritance allows us to use padding across classes.

Move FullSourceLoc::dump into the .cpp file, the used attribute made us emit this into every TU that includes SourceLocation.h.

vector::emplace_back was mistakenly requiring move assignable.  Fixed that and did a little drive-by optimization at the same time.  This fixes http://llvm.org/bugs/show_bug.cgi?id=12085.

Debian multiarch libraries, this should in theory add support for those
platform's header search rules. I don't have a system to check this
with, so review appreciated. I've added the corresponding tests
referring to the debian multiarch tree.

We are starting to have a relatively completely tested Linux platform
for header search and library search, with several interesting
peculiarities. We should point people at the debian_multiarch_tree when
suggesting new tests. Folks with Debian systems that can check this for
correctness, it would be much appreciated. The missing chunks I know of
are testing bi-arch peudo-cross-compiling toolchains betwen 32-bit and
64-bit variants of platforms, and the MIPS and ARM Debian toolchains.

 - variant members with nontrivial destructors make the containing class's
   destructor deleted
 - check for a virtual destructor after checking for overridden methods in the
   base class(es)
 - check for an inaccessible operator delete for a class with a virtual
   destructor.

Do not try to call an anonymous union field's destructor from the destructor of
the containing class.
