The ptrto field of the type data cannot be relied on when dynamic linking: a
type T may be defined in a module that makes no use of pointers to that type,
but another module can contain a package that imports the first one and does use
*T pointers.  The second module will end up defining type data for *T and a
type.*T symbol pointing at it. It's important that calling .PtrTo() on the
refect.Type for T returns this type data and not some synthesized object, so we
need reflect to be able to find it!

Fortunately, the reflect package already has a mechanism for doing this sort of
thing: ChanOf/MapOf/etc look for pre-existing type data by name.  So this change
just extends PtrTo() to consult this too, and changes the compiler to include
pointer types in the data consulted when compiling for dynamic linking.

7g and 9g disagree with componentgen
about what type len and cap have.

This results in an etype mismatch,
which inhibits registerization.

Fixing this results in 7406 more registerizations
while building the stdlib.
There are still 1512 missed opportunities.

This should improve the performance benefit
to 7g of enabling componentgen (CL 8636).

This CL reduces the size of godoc by 203k (-1.177%).

This was discovered by using the diagnostics
added in CL 8732 and running:

GOARCH=arm64 GOOS=linux go build -gcflags="-d registerization" std

See CL 91850043 for similar earlier fixes for 6g and 8g.

CGO_ENABLED=0.

This change makes disableSocketConnect take a look at not only address
family but socket type for fixing some dial tests with -ipv6 when
CGO_ENBALED=0.
