malloc: Fix for infinite loop in memalign/posix_memalign.
A very large alignment argument passed to mealign/posix_memalign
causes _int_memalign to enter an infinite loop. Limit the maximum
alignment value to the maximum representable power of two to
prevent this from happening.
Changelog:

[BZ #16038]
* malloc/hooks.c (memalign_check): Limit alignment to the
maximum representable power of two.
* malloc/malloc.c (__libc_memalign): Likewise.
* malloc/tst-memalign.c (do_test): Add test for very
large alignment values.
* malloc/tst-posix_memalign.c (do_test): Likewise.
