[dev.cc] runtime: convert defs_$GOOS_$GOARCH.h to Go

The conversion was done with an automated tool and then
modified only as necessary to make it compile and run.

In a few cases, defs_$GOOS_$GOARCH.go already existed,
so the target here is defs1_$GOOS_$GOARCH.go.

[This CL is part of the removal of C code from package runtime.
See golang.org/s/dev.cc for an overview.]
