48b13291d1 add bv-size reduce #6137 
- add option smt.bv.reduce_size.
  - it allows to apply incremental pre-processing of bit-vectors by identifying ranges that are known to be constant.
    This rewrite is beneficial, for instance, when bit-vectors are constrained to have many high-level bits set to 0.

parallel-tactic: fix deadlocking race between shutdown and get_task (#6152) 
Deadlock/Race is as follows:
  1. get_task() reads m_shutdown == false and enters loop body
  2. shutdown() is called; sets m_shutdown = true
  3. shutdown() calls m_cond.notify_all()
  4. get_task() finds no task in try_get_task()
  5. get_task() calls m_cond.wait(), missing the notification
  6. solve() waits forever on join()

Provided patch wraps (2) and (3) with the condition variable lock so that
step (5) cannot miss the notification.

fc77345bec breaking change. Enforce append semantics everywhere for parameter updates #5744 
Replace semantics doesn't work with assumptions made elsewhere in code.
The remedy is to apply append (override) semantics for parameter changes.
