Add initial support for the FreeBSD/alpha kernel. This is very much a work in progress and has never booted a real machine. Initial development and testing was done using SimOS (see http://simos.stanford.edu for details). On the SimOS simulator, this port successfully reaches single-user mode and has been tested with loads as high as one copy of /bin/ls :-). Obtained from: partly from NetBSD/alpha

Add new functions fill_fpregs() and set_fpregs(), like fill_regs() and set_regs() but for the floating point register state. The code is stolen from procfs_machdep.c, and moved out of there into machdep.c. These functions are needed for generating ELF core dumps.
