5a9d56ab90 Update Triple to use StringRef/Twine based APIs.
- This is now shorter, simpler, safer, and more efficient, what a deal.

values.  Hopefully this fixes PR4622.

da42799098 Add a missing ilist_node.h #include to SparseBitVector, and add a very short
test for it. The test is by no means complete, but it tests the problem I was
fixing.

b5adc13728 Convert StringMap to using StringRef for its APIs.
- Yay for '-'s and simplifications!

 - I kept StringMap::GetOrCreateValue for compatibility purposes, this can
   eventually go away. Likewise the StringMapEntry Create functions still follow
   the old style.

 - NIFC.

b500f07edf Make the JIT code emitter properly retry and ask for more memory when it runs
out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

4c892c05ec Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

ec10fcbd04 Replace intersectWith with maximalIntersectWith. The latter guarantees that
all values belonging to the intersection will belong to the resulting range.
The former was inconsistent about that point (either way is fine, just pick
one.) This is part of PR4545.

393d8b0a0c 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.

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.

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.

this behavior.

A patch to allocate additional memory for globals after we run out is
forthcoming.
