The existing CompEnd predicate does not define a strict weak order as required
by the C++03 standard; therefore, its use as a predicate to std::upper_bound
is invalid. For a discussion of this issue, see
http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#270
This patch replaces the asymmetrical comparison with an iterator adaptor that
achieves the same effect while being strictly standard-conforming by ensuring
an apples-to-apples comparison.

lowering of objectsize intrinsics. Unfortunately, a number of tests were relying
on llc not optimizing trivial branches, so I had to add an option to allow them
to continue to test what they originally tested.
This fixes <rdar://problem/8785296> and <rdar://problem/9112893>.

Still need to add "in methods of a class" to the specifiers, and the ability to write the stop hooks in the Scripting language as well as in the Command Language.

CodeGenRegister entries. Use this information to more intelligently build
the literal register entires in the DAGISel matcher table. Specifically,
use a single-byte OPC_EmitRegister entry for registers with a value of
less than 256 and OPC_EmitRegister2 entry for registers with a larger value.

SBTarget.Launch() API, stop at a breakpoint, get the stopped thread, and verify that the
pid of the stopped thread's process is equal to the pid of the process returned by
SBTarget.Launch().

correct order. Previously this was tacitly implemented but not
enforced, so it was possible to accidentally do things in the wrong
order and cause problems. This fixes that problem.

Value, not an Instruction, so casting is not necessary. Also,
it's theoretically possible that the Value is not an
Instruction, since WeakVH follows RAUWs.

in the LLVM test suite, this function was consuming 7.4% of -fsyntax-only time. This change fixes this issue
by delaying the check that the warning would be issued within a system macro by as long as possible. The
main negative of this change is now the logic for this check is done in multiple places in this function instead
of just in one place up front.

after it has finished all of its reassociations, because its
habit of unlinking operands and holding them in a datastructure
while working means that it's not easy to determine when an
instruction is really dead until after all its regular work is
done. rdar://9096268.

This happens a lot in clang-compiled C++ code because it adds overflow checks to operator new[]:
unsigned *foo(unsigned n) { return new unsigned[n]; }
We can optimize away the overflow check on 64 bit targets because (uint64_t)n*4 cannot overflow.
