Log Message:
Improve the dodgy code that writes the FP regs into core dumps of 32bit apps.
(I'm not pretending it is correct yet!)
The 'struct fpreg32' (written to coredumps) is shorter than 'struct save87'
so netbsd32_process_read_fpregs() hadn't better write to the extra items.
Doing so overwrites stack in coredump_note() in core_elf32.c - I'm amazed
it doesn't cause a panic!
Also correct (I think) the code and data addresses associated with the FP
unit.
This probably wants pulling up.
