compiler: make value method of direct interface type takes pointer
Currently, a value method of a direct interface type takes the
value of the receiver, which is pointer shaped, as the first
parameter. When this method is called through interface, we
actually pass the interface data as a pointer. On most platforms
this is ok, as the underlying calling convention is the same,
except that on SPARC32, the calling convention is actually
different.
This CL changes the method function actually takes a pointer.
The function will convert the pointer to the pointer-shaped
receiver type (a no-op conversion from machine code's aspect).
For a direct call, in the caller we convert the receiver to a
pointer (also no-op conversion) before invoking the method. For
an interface call, we pass the pointer as before. This way, it is
consistent that we always pass a pointer.
Hopefully this fixes SPARC32 build and https://gcc.gnu.org/PR90482.

Implicit interface conversions were mostly added late in the
compilation pipeline, after the escape analysis. For the escape
analysis to see them, we move the introduction of these
conversions earlier, right before the escape analysis.
Now that the compiler can generate interface conversions inlined,
gcc/testsuite/go.test/test/nilptr2.go needs to be adjusted as in
golang.org/cl/176579, so the use function does an actual use.

* go.test/test/nilptr2.go: Change use function to actually do
something.
