[dev.typeparams] test: fix and update run.go's generics testing In a late change to golang.org/cl/320609, while going back and forth on the meaning of the boolean result value for "checkFlags", I got one of the cases wrong. As a result, rather than testing both default flags and -G=3, we were (redundanly) testing default flags and -G=0. I ran into this because in my local dev tree, I'm using types2 even for -G=0, and evidently one of the recent types2 CLs changed the error message in fixedbugs/issue10975.go. Fortunately, there haven't been any other regressions despite lacking test coverage. So this CL cleans things up a bit: 1. Fixes that test to use -lang=go1.17, so types2 reports the old error message again. 2. Renames "checkFlags" to "validForGLevel" so the boolean result is harder to get wrong. 3. Removes the blanket deny list of all -m tests, and instead adds the specific tests that are still failing. This effectively extends -G=3 coverage to another 27 tests that were using -m but already passing, so we can make sure they don't regress again. 4. Adds a -f flag to force running tests even if they're in the deny list, to make it easier to test whether they're still failing without having to edit run.go.

[dev.typeparams] all: merge dev.regabi into dev.typeparams The files below had conflicts that required manual resolution. The unresolved conflict in noder.go was just in the import declaration (trivial). All the other conflicts are in tests where the ERROR regex patterns changed to accomodate gccgo error messages (incoming from dev.regabi), and to accomodate types2 in dev.typeparams. They were resolved by accepting the dev.regabi changes (so as not to lose them) and then by re- applying whatever changes needed to make them pass with types2. Finally, the new test mainsig.go was excluded from run.go when using types2 due to issue #43308. src/cmd/compile/internal/gc/noder.go test/fixedbugs/bug13343.go test/fixedbugs/bug462.go test/fixedbugs/issue10975.go test/fixedbugs/issue11326.go test/fixedbugs/issue11361.go test/fixedbugs/issue11371.go test/fixedbugs/issue11674.go test/fixedbugs/issue13365.go test/fixedbugs/issue13471.go test/fixedbugs/issue14136.go test/fixedbugs/issue14321.go test/fixedbugs/issue14729.go test/fixedbugs/issue15898.go test/fixedbugs/issue16439.go test/fixedbugs/issue17588.go test/fixedbugs/issue19323.go test/fixedbugs/issue19482.go test/fixedbugs/issue19880.go test/fixedbugs/issue20185.go test/fixedbugs/issue20227.go test/fixedbugs/issue20415.go test/fixedbugs/issue20749.go test/fixedbugs/issue22794.go test/fixedbugs/issue22822.go test/fixedbugs/issue22921.go test/fixedbugs/issue23823.go test/fixedbugs/issue25727.go test/fixedbugs/issue26616.go test/fixedbugs/issue28079c.go test/fixedbugs/issue28450.go test/fixedbugs/issue30085.go test/fixedbugs/issue30087.go test/fixedbugs/issue35291.go test/fixedbugs/issue38745.go test/fixedbugs/issue41247.go test/fixedbugs/issue41440.go test/fixedbugs/issue41500.go test/fixedbugs/issue4215.go test/fixedbugs/issue6402.go test/fixedbugs/issue6772.go test/fixedbugs/issue7129.go test/fixedbugs/issue7150.go test/fixedbugs/issue7153.go test/fixedbugs/issue7310.go test/fixedbugs/issue8183.go test/fixedbugs/issue8385.go test/fixedbugs/issue8438.go test/fixedbugs/issue8440.go test/fixedbugs/issue8507.go test/fixedbugs/issue9370.go test/fixedbugs/issue9521.go Change-Id: I26e6e326fde6e3fca5400711a253834d710ab7f4 2020-12-21 14:41:23 -07:00			`int // ERROR "interface contains embedded non-interface\|not an interface"`
