src: Add support for 64-bit version of Plan 9 This set of changes extends the Plan 9 support to include the AMD64 architecture and should work on all versions of Plan 9. R=golang-dev, rminnich, noah.evans, rsc, minux.ma, npe CC=akskuma, golang-dev, jfflore, noah.evans https://golang.org/cl/6479052

runtime: use new #include "textflag.h" I did this just to clean things up, but it will be important when we drop the pkg directory later. LGTM=bradfitz R=r, bradfitz CC=golang-codereviews https://golang.org/cl/132600043

#include "textflag.h"
runtime: convert .s textflags from numbers to symbolic constants. Remove NOPROF/DUPOK from everything. Edits done with a script, except pclinetest.asm which depended on the DUPOK flag on main(). R=golang-dev, bradfitz CC=golang-dev https://golang.org/cl/12613044

liblink, runtime: preliminary support for plan9/amd64 A TLS slot is reserved by _rt0_.*_plan9 as an automatic and its address (which is static on Plan 9) is saved in the global _privates symbol. The startup linkage now is exactly like that from Plan 9 libc, and the way we access g is exactly as if we'd have used privalloc(2). Aside from making the code more standard, this change drastically simplifies it, both for 386 and for amd64, and makes the Plan 9 code in liblink common for both 386 and amd64. The amd64 runtime code was cleared of nxm assumptions, and now runs on the standard Plan 9 kernel. Note handling fixes will follow in a separate CL.

runtime: convert a few traceback-related functions from proc.c to traceback.go They were in proc.c mainly because there was no portable traceback source file. As part of converting them to Go, move to traceback.go. In order to get access to the PC of _rt0_go, rename to runtime.rt0_go.
