[COMMITTED 0/4] alpha updates

[Richard Henderson <rth at twiddle dot net>]

There are a number of new failures in the math tests, despite the
ulps update.  I suspect some sort of qemu bug, but I've not yet
fully investigated.

The __pointer_chk_guard change fixes some conficting declaration
errors within the testsuite.  Dunno how long I've not noticed that.

Similarly with the backtrace tests.  Somehow I'd thought that alpha
already had unwind tables enabled by default, but clearly not.  I
really should think about fixing that by default in gcc.

Finally, the pthread_once algorithm is identical to the default.
While open-coding the load-lock/store-conditional makes for a bit
smaller code, I can't imagine that benefit is worth maintaining a
separate version.
