Add a way to get the context of any particular scope.

Add preliminary support for hashing DIEs and breaking them into
type units.

Initially this support is used in the computation of an ODR checker
for C++. For now we're attaching it to the DIE, but in the future
it will be attached to the type unit.

This also starts breaking out types into the separation for type
units, but without actually splitting the DIEs.

In preparation for hashing the DIEs this adds a DIEString type
that contains a StringRef with the string contained at the label.

Move this to the X86 directory, unfortunately the hashes are not
endian independent.

Re-add DataLayout pointer size convenience functions.

These were reverted in r167222 along with the rest
of the last different address space pointer size attempt.
These will be used in later commits.
