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.

default, this option is not enabled to support clients who rely on
this behavior.

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

Also don't call finalizers for LoopPass if initialization was not called.
Add a unittest that tests that these methods are called, in the proper
order, and the correct number of times.

emitted or the machine code for a function is freed.  Chris mentioned that we
may also want a notification when a stub is emitted, but that'll be a future
change.  I intend to use this to tell oprofile where functions are emitted and
what lines correspond to what addresses.

the comparison operators were not only unnecessary in the presence of the
implicit conversion; they caused ambiguous overload errors. So I deleted them.

ConstantInt::getSigned(Ty, int64_t) method. Just overloading
ConstantInt::get() to take an int64_t too would cause ambiguous
overload errors."

Also, if you wish to debate the proper names of the triple components
I'm all ears.
