08d55342e3 Don't use std::copy and std::copy_backward, run 10% faster. 
Sometimes std::copy can become a memmove call, and that is not a good idea when
copying relatively few bytes as we are doing. We also get a small win by
changing two loops into one.

5f456cda98 Disallow overlapping inserts, even when inserting the same value. 
We always disallowed overlapping inserts with different values, and this makes
the insertion code smaller and faster.

If an overwriting insert is needed, it can be added as a separate method that
trims any existing intervals before inserting. The immediate use cases for
IntervalMap don't need this - they only use disjoint insertions.

b0b7214fc9 Add test case with randomly ordered insertions, massive coalescing. 
Implement iterator::erase() in a simple version that erases nodes when they
become empty, but doesn't try to redistribute elements among siblings for better
packing.

Handle coalescing across leaf nodes which may require erasing entries.

the compiler is clever enough to remove it.)
