cmd/compile/internal/syntax: remove code dealing with multiple method names When parsing method declarations in an interface, the parser has for historic reasons gracefully handled a list of method names with a single (common) signature, and then reported an error. For example interface { m1, m2, m3 (x int) } This code originally came from the very first parser for Go which initially permitted such declarations (or at least assumed that people would write such declarations). Nobody is doing this at this point, so there's no need for being extra careful here. Remove the respective code and adjust the corresponding test.
