Replace -dag-chain-limit flag with constant. It has survived a release cycle without being touched, so no longer needs to pollute the hidden-help text.

ComputeMaskedBits: sub falls through to add, and sub doesn't have the same overflow semantics as add.

Should fix the selfhost failures that started with r127463.

InstCombine: Fix a thinko where transform an icmp under the assumption that it's a zero comparison when it's not.

Fixes PR9454.

do with nuw here, but sub and mul should be given similar treatment.
Fixes PR9343 #15!

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>.

Add a first pass at a "stop hook" mechanism.  This allows you to add commands that get run every time the debugger stops, whether due to a breakpoint, the end of a step, interrupt, etc.  You can also specify in which context you want the stop hook to run, for instance only on a particular thread, or only in a particular shared library, function, file, line range within a file.

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.

CommandInterpreter::HandleCommands should take its commands as a "const StringList &" since it doesn't modify it...

Also, don't turn on the immediate output in the temporary result, or you'll get doubled output.
