be1e5d3113 PowerPC LE setjmp/longjmp
http://sourceware.org/ml/libc-alpha/2013-08/msg00089.html

Little-endian fixes for setjmp/longjmp.  When writing these I noticed
the setjmp code corrupts the non volatile VMX registers when using an
unaligned buffer.  Anton fixed this, and also simplified it quite a
bit.

The current code uses boilerplate for the case where we want to store
16 bytes to an unaligned address.  For that we have to do a
read/modify/write of two aligned 16 byte quantities.  In our case we
are storing a bunch of back to back data (consective VMX registers),
and only the start and end of the region need the read/modify/write.

	[BZ #15723]
	* sysdeps/powerpc/jmpbuf-offsets.h: Comment fix.
	* sysdeps/powerpc/powerpc32/fpu/__longjmp-common.S: Correct
	_dl_hwcap access for little-endian.
	* sysdeps/powerpc/powerpc32/fpu/setjmp-common.S: Likewise.  Don't
	destroy vmx regs when saving unaligned.
	* sysdeps/powerpc/powerpc64/__longjmp-common.S: Correct CR load.
	* sysdeps/powerpc/powerpc64/setjmp-common.S: Likewise CR save.  Don't
	destroy vmx regs when saving unaligned.
