This should result in less indirect memory accesses, less dead writes and tighter code.

of MachineInstr def operands must be subtracted out. This bug
was uncovered by the recent x86 EFLAGS optimization. Before
that, the only instructions that ever needed unfolding were
things like CMP32rm, where NumDefs is zero.

  on failure to resolve it.
Do not abort on failure to resolve an external symbol when using dlsym stubs,
  since the symbol may not be in the JIT's address space.  Just use 0.
Allow dlsym stubs to differentiate between GlobalVars and Functions.

Partial fix for <rdar://problem/6645157> [clang on Xcode; regression]: error: instance variable 'someField' is private.

A recent regression caused by http://llvm.org/viewvc/llvm-project?rev=65912&view=rev.

This commit isn't fully baked. Nevertheless, it should cause Xcode to compile again. Will speak with Fariborz offline.

BlockModule.  No functionality change.  This should help people that
don't want to know anything about blocks not be confused by the
overloaded use of the term block or nor want to see all the blocks

Finish up some fixes related to <rdar://problem/6497631> Message lookup is sometimes different than gcc's.

- Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch).
- Tighten up lookup when messaging 'self'.

Add a restore folder, which shaves a dozen or so machineinstrs off oggenc.  Update a testcase to check this.

 - Add Options.def file, collects option information.

 - Actual option instantiation is handled lazily by OptTable to allow
   the driver to not need to instantiate all options.

 - cast<> support for Option, other minor tweaks.

this ilist-embedded sentinel technique before me :-)
