df88fc6109 arm: bugfixes and syscall 
- integer divide by zero raises panic
- float comparisons involving NaNs work

e473f42b2d amd64: use segment memory for thread-local storage 
Returns R14 and R15 to the available register pool.
Plays more nicely with ELF ABI C code.
In particular, our signal handlers will no longer crash
when a signal arrives during execution of a cgo C call.

Fixes #720.

Fixes flaky crashes with messages like

throw: malloc mlookup

throw: unwindstack on self
throw: free mlookup

(and probably others) when running cgo.

3c32300c4d runtime: update godefs usage comment for GOARCH=386 GOOS={darwin,freebsd} 
When trying to regenerate src/pkg/runtime/darwin/386/defs.h
on a 64 bit capable Snow Leopard (OS X 10.6.3) system I
needed to add -f -m32 to godefs, as this OS and hardware
combination defaults to 64 bit compilation.

For safety, make the same change to the 32 bit FreeBSD
instructions in .../freebsd/defs.c.  (Tested OK and no
problems introduced.)
