Subject: [PATCH] Simplifier: do not create extractbits with pointer or floatbv
 type

This is a fix-up for 525c23dc7ce: we must not remove typecasts towards
pointers (or floatbv) when the operand is extractbits as our back-ends
do not support extractbits with pointer type and casts towards floatbv
are non-trivial.
