* malloc/malloc.c (chunk2mem_check, top_check): New functions.
(malloc_check, free_check, realloc_check, memalign_check): Use
them to improve overrun checking. Overruns of a single byte and
corruption of the top chunk are now detected much more reliably.

* math/libm-test.c (pow_test): Add test for special value from PR
libc/590.
