When forming sentinels for empty/tombstone, make sure to respect the

pointer's expected number of zero low-bits.
This should fix the breakage I introduced recently.

some pointer instances have properties that not all of a type have.

Replace the PointerLikeTypeTraits::getNumLowBitsAvailable
...
function with a new NumLowBitsAvailable enum, which makes the
value available as an integer constant expression.
Add PointerLikeTypeTraits specializations for Instruction* and
Use** since they are only guaranteed 4-byte aligned.
Enhance PointerIntPair to know about (and enforce) the alignment
specified by PointerLikeTypeTraits. This should allow things
like PointerIntPair<PointerIntPair<void*, 1,bool>, 1, bool>
because the inner one knows that 2 low bits are free.

Use intptr_t instead of unsigned here, which is more appropriate
...
in a really obscure way, but more importantly has the side effect
of avoiding a GCC warning in the case that IntType is bool.
