Robert Griesemer 912a638b0c cmd/compile: check labels and branches during parse time ... Instead of a separate check control flow pass (checkcfg.go) operating on nodes, perform this check at parse time on the new syntax tree. Permits this check to be done concurrently, and doesn't depend on the specifics of the symbol's dclstack implementation anymore. The remaining dclstack uses will be removed in a follow-up change. - added CheckBranches Mode flag (so we can turn off the check if we only care about syntactic correctness, e.g. for tests) - adjusted test/goto.go error messages: the new branches checker only reports if a goto jumps into a block, but not which block (we may want to improve this again, eventually) - also, the new branches checker reports one variable that is being jumped over by a goto, but it may not be the first one declared (this is fine either way) - the new branches checker reports additional errors for fixedbugs/issue14006.go (not crucial to avoid those errors) - the new branches checker now correctly reports only variable declarations being jumped over, rather than all declarations (issue 8042). Added respective tests. Fixes #8042.
