more 386 runtime: remove use of _subv in vlrt.c darwin/386/signal.c darwin/386/* linux/386/* (forgotten before) can run empty program on darwin/386 now. R=r DELTA=1140 (1021 added, 114 deleted, 5 changed) OCL=26942 CL=26968

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

runtime: change 386 startup convention Now the default startup is that the program begins at _rt0_386_$GOOS, which behaves as if calling main(argc, argv). Main jumps to _rt0_386. This makes the _rt0_386 entry match the expected semantics for the standard C "main" function, which we can now provide for use when linking against a standard C library. 386 analogue of https://golang.org/cl/7525043 R=golang-dev, r CC=golang-dev https://golang.org/cl/7551045

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.
