XairRrR 91bbd2fca5 fix(shader): poison an SRT read below a pointer loaded from memory

A read at a negative offset from a pointer the walker loaded from guest
memory (a null pointer behind a guarded branch, offset -4) wrapped below
zero in AddSignedAddress, and the walk threw "cannot evaluate" instead of
recording the read as inaccessible. Uncharted: The Lost Legacy threw it
while loading its first level. The read is now recorded as an SRT poison
at its address wrapped to 48 bits, like any other unreadable address, so
the binding faults only if the shader takes that path.

verifyGuardedNullPointers gains the case for both branch outcomes; it
throws the title's error without the change.
