Subject: [PATCH 10/17] arm: user_regset: VFP in core dumps

This enables dumping the VFP state in ELF core dumps.
It gets its own note.

I reused the NT_PRXFPREG type code already used for extended-FP
state on x86, because it seems to fit logically.  It would be just
as easy to define a new code called NT_ARM_VFP in linux/elf.h if
that is preferable.
