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: rename _rt0_$GOARCH to _rt0_go There's no reason to use a different name on each architecture, and doing so makes it impossible for portable code to refer to the original Go runtime entry point. Rename it _rt0_go everywhere. This is a global search and replace only. R=golang-dev, bradfitz, minux.ma CC=golang-dev https://golang.org/cl/10196043
