f1db120d04 Multiply was very wrong for wrapped ranges. This supplies a half-fix that will 
generally return Full on all wrapped inputs. "Fixes" PR4545.

cf9e07dea8 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!

 - Minor tweak by me to add llvm_unreachable calls on FIXMEd error paths.

c25e7581b9 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

646ca92bfc Fix handling of max and full set. 
A full set is a constant range that represents any number. If you take the
umax of that and [5, 10) you end up with [5, INT_MAX] because the values less
than 5 would be umax's against a value which is at least 5.

bf8c7f0adf Move a method that creates constant ranges relative to another constant range 
per icmp predicate out of predsimplify and into ConstantRange.

Add another utility method that determines whether one range is a subset of
another. Combine with the former to determine whether icmp pred range, range
is known to be true or not.

a3755d8d36 Add a ConstantSignedRange class, which does for signed integers 
what ConstantRange does for unsigned integers. Factor out a

ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.

This will replace exit()/abort() style error handling with an API
that allows clients to register custom error handling hooks.

cf2a2c6a26 raw_ostream: Lift out flush_nonempty. 
- Flush a known non-empty buffers; enforces the interface to
   flush_impl and kills off HandleFlush (which I saw no reason to be
   an inline method, Chris?).

 - Clarify invariant that flush_impl is only called with OutBufCur >
   OutBufStart.

 - This also cleary collects all places where we have to deal with the
   buffer possibly not existing.

 - A few more comments and fixing the unbuffered behavior remain in
   this commit sequence.

d52ec65b6d Fix a hashing bug in APInt. A certain pathological testcase (too 
large for the testsuite) took over six minutes to compile on my Mac.
The patched LLVM-GCC compiles that testcase in three seconds (GCC
takes less than one second).  This hash function is more complex
(about 35 instructions on x86) than what Chris wanted, but I expect it
will be well-behaved with arbitrary inputs.

Thank you to everyone who responded to my previous request for advice.
