995f9a8a15 Improve sys::Path::makeAbsolute on Win32. 
- Patch by Viktor Kutuzov!

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

ae8a3ff177 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.

3e43cd4105 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.

fee40fdcd9 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.

a60479705b Make changes suggested by Chris and eliminate newly-added raw_ostream 
hooks as they're no longer needed.

The major change with this patch is to make formatted_raw_ostream usable
by any client of raw_ostream.

98610d5cfd Add some hooks that a redesigned AsmStream needs to do its job. These 
allow derived classes to examine the stream buffer before it's flushed.

8a58b8f83b Revert the part of 75177 that split ConstantRange into two classes, and 
merge the new functionality and unittests into ConstantRange. Thanks to
Nick Lewycky for pointing out that it isn't necessary to have two separate
classes here.

33251eff97 Add a ConstantSignedRange class, which does for signed integers 
what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.

Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.

with very large graphs, where dot isn't necessarily the 
most visually pleasing way of looking at the graph.

d185fbe8a1 Allow users of GraphWriter to display graphs asynchronously. This 
provides a way to quickly dump a bunch of graph information to dot files
and display them.  It's a timesaver when working on large systems.

375564339a Introduce new error handling API. 
This will replace exit()/abort() style error handling with an API
that allows clients to register custom error handling hooks.
The default is to call exit(1) when no error handler is provided.

1e3e84eb39 add an explicit class for holding llvm::SourceMgr diagnostics and use 
it to print them.  This gives us column numbers in the diag line.  Before:

t.s:4: error: unexpected token in argument list
 mov %eax %edx
          ^

now:
t.s:4:11: error: unexpected token in argument list
 mov %eax %edx
          ^

5bec168037 Normalize SourceMgr messages. 
- Don't print "Parsing" in front of every message.

 - Take additional "type" argument which is prepended to the message (with ": ")
   if given.

 - Update clients to print errors (warnings) as:
<filename>:<line number>: error(warning): ...

226e1d8bda Make timers threadsafe again. This isn't quite as nice as I'd hoped (it uses locking rather than atomic arithmetic), 
but should work on all the platforms we care about.

I might revisit this if a totally awesome way to do it occurs to me.
