Fix CPPFLAGS in test Makefile
...
In particular, the _GNU_SOURCE feature test macro needs to be set in
order to correctly define mmap(2) flags such as MAP_ANONYMOUS.
Otherwise, compilation of some test files fails when CPPFLAGS is not
defined in the initial user environment, as Make then does not export it
from the root Makefile to the sub-make.

avoid undefined clz and shift in edge cases
...
This is triggered when get_large_size_class is called with a size in the
range [1,4]. This can occur with aligned_alloc(8192, size). In practice,
it doesn't appear to cause any harm, but we shouldn't have any undefined
behavior for well-defined usage of the API. It also occurs if the caller
passes a pointer outside the slab region to free_sized but the expected
size is in the range [1,4]. That usage of free_sized is already going to
be considered undefined, but we should avoid undefined behavior in the
caller from triggering more undefined behavior when it's avoidable.
