Following 3a839517ce, SparseGrid::Reset() replaces the value of m_Data
(a C-style dynamically sized array) with a new value-initialised array,
by using the new operator. Previous code simply did a memset.
This means that when m_Data was not null, it leaked memory as the
previous array was not deleted.
SparseGrid::Reset is called when destroying the sparse grid, and a
SparseGrid is used by the long pathfinder when computing JPS paths. As
that is called rather often, it resulted in a relatively serious memory
leak that could make very long games use several GB of memory.
This fixes the leak by using placement new, which re-uses the memory,
effectively doing the same as the previously existing memset.
Profiling by historic_bruno and elexis showed that performance from
value-initialising with placement new was at worst similar to memset,
and testing shows this was compiled in a memset call in several cases
anyways.

This was SVN commit r22545.
By adding a custom function in Grid, the code gets vectorised on both
gcc and clang, resulting in much faster code and faster update times,
sometimes substantially (on giant maps or when few chunks must be
updated).

The bug came from inlining the copy constructor of Grid, which ended up
reading from un-initialized variables.

the old debug_assert always ran and tested the expression, which slows
down release builds. wrapping them in #ifndef NDEBUG is clumsy. the new
ASSERT behaves like assert and ENSURE like the old debug_assert. Let's
change any time-critical but not-super-important ENSURE to ASSERT to
speed up release builds. (already done in bits.h and unique_range.h)
