fd095b6389 Get rid of the tagging functions and use PointerIntPair.
This means that we have to include an additional header.

This patch should be functionally equivalent. I cannot outrule any performance
degradation, though I do not expect any.

023f84ecaf Introduce a typing refinenement on tagged data
using the 'volatile' qualifier. This should not have any operational consequences
on code, because tags should always be stripped off (giving a non-volatile pointer)
before dereferencing. The new qualification is there to catch some attempts to use
tagged pointers in a context where an untagged pointer is appropriate.

Notably this approach does not catch dereferencing of tagged pointers, but helps
in separating the two concepts a bit.

6c2c95d0ac first shot at removing Use::Val
untested, Use::swap() is definitely not done yet

94fb68ba21 Merge of r51073-51074 from use-diet branch.
Do not rely on std::swap<Use>, provide a (faster) member function instead.
This change is primarily necessitated by MSVC++'s incompatibility with
declaring std::swap<Use> to be a friend of Use.

Also contains some minor tweaks to Use inline functions,
to undo pointless changes that sneaked in with the last merge.
