Prior to this CL, flags such as NOSPLIT on ATEXT Progs were stored in From3.Offset. Some but not all of those flags were also duplicated into From.Sym.Attribute. This CL migrates all of those flags into From.Sym.Attribute and stops creating a From3. A side-effect of this is that printing an ATEXT Prog can no longer simply dump From3.Offset. That's kind of good, since the raw flag value wasn't very informative anyway, but it did necessitate a bunch of updates to the cmd/asm tests. The reason I'm doing this work now is that avoiding storing flags in both From.Sym and From3.Offset simplifies some other changes to fix the data race first described in CL 40254. This CL almost passes toolstash-check -all. The only changes are in cases where the assembler has decided that a function's flags may be altered, e.g. to make a function with no calls in it NOSPLIT. Prior to this CL, that information was not printed. Sample before: "".Ctz64 t=1 size=63 args=0x10 locals=0x0 0x0000 00000 (/Users/josh/go/tip/src/runtime/internal/sys/intrinsics.go:35) TEXT "".Ctz64(SB), $0-16 0x0000 00000 (/Users/josh/go/tip/src/runtime/internal/sys/intrinsics.go:35) FUNCDATA $0, gclocals·f207267fbf96a0178e8758c6e3e0ce28(SB) Sample after: "".Ctz64 t=1 nosplit size=63 args=0x10 locals=0x0 0x0000 00000 (/Users/josh/go/tip/src/runtime/internal/sys/intrinsics.go:35) TEXT "".Ctz64(SB), NOSPLIT, $0-16 0x0000 00000 (/Users/josh/go/tip/src/runtime/internal/sys/intrinsics.go:35) FUNCDATA $0, gclocals·f207267fbf96a0178e8758c6e3e0ce28(SB) Observe the additional "nosplit" in the first line and the additional "NOSPLIT" in the second line.
