Ulrich Drepper bec466d922 Fix race in corruption check. 
With atomic fastbins the checks performed can race with concurrent
modifications of the arena.  If we detect a problem re-do the test
after getting the lock.

Jakub Jelinek bea0ac1d87 Use rel semantics of cas instead of acq semantics with full barrier before it in _int_free 
The following patch fixes catomic_compare_and_exchange_*_rel definitions
(which were never used and weren't correct) and uses
catomic_compare_and_exchange_val_rel in _int_free.  Comparing to the
pre-2009-07-02 --enable-experimental-malloc state the generated code should
be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use
lwsync instead of isync barrier.

	[BZ #4349]
	* malloc/malloc.c: Keep separate list for first blocks on the bin
	lists with a given size.  This helps skipping over list elements
	we know won't fit in two places.
	Inspired by a patch by Tomash Brechko <tomash.brechko@gmail.com>.
