[PATCH 3/5] scheck: constants are untyped

[Luc Van Oostenryck <lucvoo@kernel.org>]

From: Luc Van Oostenryck <luc.vanoostenryck@gmail.com>

in sparse, constants (PSEUDO_VALs) are not typed, so the same pseudo
can be used to represent 1-bit 0, 8-bit 0, 16-bit 0, ...

That's incompatible with the bit vectors used here, so we can't associate
a PSEUDO_VAL with its own bitvector like it's done for PSEUDO_REGs.
A fresh one is needed for each occurrence (we could use a small table
but won't bother).
