* keep coherent SP/PC in gobuf
(i.e., SP that would be in use at that PC)
* gogocall replaces setspgoto,
should work better in presence of link registers
* delete unused system calls
only amd64; 386 is now broken

- morestack support for 5l and arm runtime
- argsize support in 5c, 5l, ar and nm. assembly code from 5a
will break in interesting ways unless NOSPLIT is specified
- explicit cond execution constants
- fix 5l output to use %d instead of %ld so that negative
values show.
- added a lot of code to arm/asm.s. runtime entry code almost
working currently aborts at gogo not implemented

* heuristic to go farther during stack traces.
* significantly improved Linux thread handing.
acid:
* update to new libmach interface.
prof:
* use new libmach interface.
* multiple thread support (derived from Rob's copy).
* first steps toward pprof-like graphs:
keep counters indexed by pc,callerpc pairs.

if you clone inside a traced pid, the child
is automatically attached and stopped,
apparently.

* add gotype string to symbol table
* fill in gotype in 6l for known funcs/vars
* print gotype with nm -t
* load symbol and pc/ln tables into memory at magic address 0x99<<32.
* add sys.symdat() to retrieve raw bytes of symbol table
and pc/ln table.
most of this should be considered experimental
and subject to change.

This makes it easy to build with other flags
(like -ggdb) or other compilers (like cc64).

these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.
(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)
the longs were rare enough that i don't think
it will cause integration problems.
