cmd/compile: fix case where g.curDecl should be saved/restored When we set g.curDecl for the type params created during fillinMethods for an instantiated type, we need to save/restore its value, because fillinMethods() may be called while processing a typeDecl. We want the value of g.curDecl to continue to be correct for type params created in the typeDecl. Because of ordering issues, not restoring g.curDecl happens to cause problems (which don't always show up visibly) exactly when a type param is not actually used in a type declaration. Cleared g.curDecl to "" at the later points in typeDecl() and funcDecl(). This allows adding asserts that g.curDecl is always empty ("") when we set it in typeDecl() and funcDecl(), and always non-empty when we use it in typ0().

test: use dot-relative imports where appropriate Currently, run.go's *dir tests allow "x.go" to be imported interchangeably as either "x" or "./x". This is generally fine, but can cause problems when "x" is the name of a standard library package (e.g., "fixedbugs/bug345.dir/io.go"). This CL is an automated rewrite to change all `import "x"` directives to use `import "./x"` instead. It has no effect today, but will allow subsequent CLs to update test/run.go to resolve "./x" to "test/x" to avoid stdlib collisions.
