Remove casts between Value** and Constant**, which won't work if a

static_cast from Constant* to Value* has to adjust the "this" pointer.
This is groundwork for PR889.

Value* were never meant to be const. Removing constness from the constant

folder removes a lot of const_casting and requires no changes to clang or

Teach lib/VMCore/ConstantFold.cpp how to set the inbounds keyword and
...
how to fold notionally-out-of-bounds array getelementptr indices instead
of just doing these in lib/Analysis/ConstantFolding.cpp, because it can
be done in a fairly general way without TargetData, and because not all
constants are visited by lib/Analysis/ConstantFolding.cpp. This enables
more constant folding.
Also, set the "inbounds" flag when the getelementptr indices are
one-past-the-end.

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.

Fix a serious bug that would cause deadlock during abstract type refinement. The constant creation
...
gets involved, and we end up trying to recursively acquire a writer lock. The fix for this is slightly horrible,
and involves passing a boolean "locked" parameter around in Constants.cpp, but it's better than having locked and
unlocked versions of most of the code.
