26043b23b0 Make room for the argument save area in _rtld_start(). The PLT stub already 
made room from _rtld_bind_start(), but add a comment explaining the instruction
it uses.

d314d82b47 Allocate space for the argument space area in both _rtld_start() and 
_rtld_bind_start().  Not needed normally, but if we compile ld.elf_so with
-g, it blows up without this.

deca50b66c Fill BADVADDR and CAUSE in sigcontext. We still don't restore them, but 
it actually fixes a problem:
When /bin/sh gets a SIGSEGV, its signal handler calls brk and the offending
instruction is retried. Usually it gets another SIGSEGV, and things loops
until it pases without the SIGSEGV. This is the normal mode of operation, and
it can be reproduced on IRIX by a 10kB shell script starting by echo /*

However... the signal handler checks for BADVADDR in the saved registers
in struct sigcontext. If it does not find it, it gives up and exit instead
of retrying. Filling the field enables us to carry on normal operation
(which is to get dozens of SIGSEGV) instead of getting a failure at the
first SIGSEGV.

e4cb5327e8 For ISA intrs 0-15, use string of the form "isa intr NN", rather than 
just "isa intr".  Having vmstat -i show multiple "isa intr" lines w/
different counts is less than desirable.  Reviewed by thorpej.

d4e6f3ff08 Swap registers %o0 and %o1 in the binder stub to say one instruction. 
Fix an obvious bug in the 64-bit PLT fixup: the SLLX was by 12 bits, when it
should be 32.

Fix what *appear* to be two bugs in the >32768 PLT entry stub:
* One division was wrong (/14 rather than /24).
* We need to subtract 1048576 (to make the offset relative to the beginning of
  the upper section), not add it.
This path is still untested, and buggy.
