when they are destroyed, which makes Constant::destroyConstant an actually
useful external interface. Expose these methods publicly.
- Implement destroyConstant on ConstPointerNull so that destroyConstant can
be used on any derived type constant safely.

* Correctly delete TypeHandles in AsmParser. In addition to not leaking
memory, this prevents a bug that could have occurred when a type got
resolved that the constexpr was using
* Check for errors in the AsmParser instead of hitting assertion failures
deep in the code
* Simplify the interface to the ConstantExpr class, removing unneccesary
parameters to the ::get* methods.
* Rename the 'getelementptr' version of ConstantExpr::get to
ConstantExpr::getGetElementPtr

constants using operators such as cast, getelementptr, add, shl, etc.
Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr. This is why isConstantExpr() is needed.

now knows how to write out a constant, not the constants themselves. This is
fixed due to the move of the AsmWriter to the VMcore library.
