cmd/ld: Put the textflag constants in a separate file.
We can then include this file in assembly to replace cryptic constants like "7" with meaningful constants like "(NOPROF|DUPOK|NOSPLIT)". Converting just pkg/runtime/asm*.s for now. Dropping NOPROF and DUPOK from lots of places where they aren't needed. More .s files to come in a subsequent changelist. A nonzero number in the textflag field now means "has not been converted yet". R=golang-dev, daniel.morsing, rsc, khr CC=golang-dev https://golang.org/cl/12568043
