operators to the lldb.value helper class.

configure was silently failing to produce anything in the case
where clang wasn't at tools/clang/, resulting in compilation
errors much later in the build when config.h didn't exist.

Fixes gdb bots for gdb1090.exp and call-ar-st.exp.

Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT.

Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches.

Adds a test to verify that the scheduler is working.

Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP.

It is simpler to define a composite index directly:

  def ssub_2 : SubRegIndex<[dsub_1, ssub_0]>;
  def ssub_3 : SubRegIndex<[dsub_1, ssub_1]>;

Than specifying the composite indices on each register:

  CompositeIndices = [(ssub_2 dsub_1, ssub_0),
                      (ssub_3 dsub_1, ssub_1)] in ...

This also makes it clear that SubRegIndex composition is supposed to be
unique.

The PROJ_SRC_DIR != PROJ_OBJ_DIR path was missing the directory
creation logic that was in the path for non-generated headers.
PR11903.

(The oversight was copied and pasted from LLVM's Makefile.rules,
where it apparently existed since time immemorial til it was
corrected in r127325.)

This header is private and shouldn't be used by clients.

(This reverts r149540, reinstating r149496. False alarm.)

The final tie breaker comparison also needs to return +/-1, or 0.
This is not a less() function.

This could cause otherwise identical super-classes to be ordered
unstably, depending on what the system qsort routine does with a bad
compare function.

This new scheduler plugs into the existing selection DAG scheduling framework. It is a top-down critical path scheduler that tracks register pressure and uses a DFA for pipeline modeling.

Remove a TODO regarding where some can_catch are implemented.  I opted to make can_catch pure virtual in the top __shim_type_info, and have each sub-class implement its own.  There are some repeated definitions, but they are trivial.

Add some tests to test catching nullptr with pointers and member pointers.  Tests are only activated if #if __has_feature(cxx_nullptr).

Quash a TODO related to catching pointer-to-member.  These tests fail on my copy of gcc-4.2.  But I believe the tests to be correct (and they pass for libc++abi).  I've enquired on the C++ standards mailing list for a clarification in case I'm wrong.  So far I've gotten one response that agrees with me.
