issues with allocations in the ContextMemoryManager:

--enable/disable-valgrind: This flag enables/disables Valgrind
instrumentation of the ContextMemoryManager. Enabled by default for
debug builds if the Valgrind headers are available.

--enable/disable-context-memory-manager: This flag enables/disables the
use of the ContextMemoryManager. If the flag is disableda dummy
ContextMemoryManager is used that does single allocations instead of
chunks. The flag is enabled by default.

Minor improvements and changes to defaults for cbqi bv (#1406)

This

makes it so that --cbqi-bv tries at most 2 instantiations per quantified formula (one based on inversions when applicable, one based on model values). This makes it so that we do not have exponential run time in the worst case. This helps significantly for psyco benchmarks which have many quantified variables.

Enables --cbqi-bv by default and changes the default inequality mode to eq-boundary (which is the best performer overall), also enables extract removal by default

Allows cbqiNestedQE to be used in the BV logic.

Adds an option --cbqi-full which indicates whether we should try model value instantiations for bit-vectors (by default, this is done only for the pure BV logic).
