Nick Lewycky 571bf54569 Fix an error in ConstantRange::getSignedMax on wrapped ranges. Thanks once 
again to Daniel Dunbar and KLEE!

Nick Lewycky 5edc459220 'i8 full-range' sign extended to i16 should equal [-128, 128) not [-128, 127). 
Found by Daniel Dunbar and KLEE.

Owen Anderson ae86c19e68 Update for LLVM API change.

Owen Anderson 53a52215b5 Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

Nick Lewycky 5302389442 Multiply was very wrong for wrapped ranges. This supplies a half-fix that will 
generally return Full on all wrapped inputs. "Fixes" PR4545.

Nick Lewycky 73b704dd9c Fix a bug summing two full sets. The overflow checking doesn't handle sets as 
large as the full set, only those one size smaller. Thanks to Daniel Dunbar
who found this bug using Klee!

Chris Lattner 7b9d6ebb9c remove llvm.part.set.* and llvm.part.select.*. They have never been 
implemented in codegen, have no frontend to generate them, and are 
better implemented with pattern matching (like the ppc backend does
to generate rlwimi/rlwinm etc).

Nick Lewycky 071e176667 This is not overly conservative.

Chris Lattner 38df005e12 fix x86-64 static codegen to materialize the address of a global with movl instead 
of lea.  It is better for code size (and presumably efficiency) to use:

  movl $foo, %eax

rather than:

  leal foo, eax

Both give a nice zero extending "move immediate" instruction, the former is just
smaller.  Note that global addresses should be handled different by the x86
backend, but I chose to follow the style already in place and add more fixme's.

Daniel Dunbar df1cff7356 Remove excessive use of Carbon.h / Cocoa.h in clang tests. 
- These kinds of "shotgun" tests are very slow, and do not belong in the
   regression suite. If these kinds of tests are regarded to have value, they
   should be added to the LLVM test-suite.

 - I would actually like to remove all of these tests, but I left Sema/carbon.c
   and SemaObjC/cocoa.m...
