compiler: statically allocate constant interface data
When converting a constant to interface, such as interface{}(42)
or interface{}("hello"), if the interface escapes, we currently
generate a heap allocation to hold the constant value.
This CL changes it to generate a static allocation instead, as
the gc compiler does. This reduces allocations in such cases.
