perf: more sharing and caching in bv_decide's reflection (#7698) 
This PR adds more sharing and caching procedures to bv_decide's
reflection step.

In particular we cache the reflection proof better, enforce better term
sharing in the reflected term, which in turn speeds up bitblasting as
bitblaster cache lookups can be checked with pointer equality. This PR
was motivated by SMTLIB problem `QF_BV/Sage2/bench_7415.smt2`
