[Reg] Make status/unsat-core detection more robust (#1775)

This commit changes the regression script to look for status patterns or
get-unsat-core/get-unsat-assumption commands in the benchmark file
instead of the metadata file (i.e. the .expect file if it exists or the
benchmark file otherwise). This fix is not strictly necessary for our
current regressions but might have lead to surprising outcomes in the
future.

Fix get-unsat-core detection in regression script (#1773)

Due to a typo in the regression script, the (get-unsat-core) command was
not recognized (the script was looking for (get-unsat-cores)), so it
tried to run a regression script containing (get-unsat-core) even when

Fix use-after-free in eager bitblaster (#1772)

There was a use-after-free in the eager bitblaster: the context used by
the SAT solver was destroyed before the solver. This lead to a
use-after-free in the destructor of the SAT solver when destroying
context-dependent objects. This commit fixes the issue by changing the
desctruction order such that the context is destroyed after the SAT
solver.

Note: This issue was introduced in commit
a917cc2ab4956b542b1f565abf0e62b197692f8d because d_nullContext and
d_satSolver were changed to be std::unique_ptrs.
