cmd/compile: do not mark arrays used for map initialization noalg Arrays marked noalg are created by the compiler to hold keys and values to initialize map literals. The ssa backend creates a pointer type for the array type when creating an OpAddr while processing the loop that initializes the map from the arrays. The pointer type does not inherit the noalg property but points to the noalg array type. This causes values created through reflect of types that should be equal to compare unequal because the noalg and alg type might be compared and these are not the same. A similar problem occurred in #32595 for argument arrays of defer structs. Created #47904 to track improve noalg handling to be able to reintroduce this optimization again.

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.
