[dev.link] cmd/internal: convert basic types to builtin symbols

The Go compiler includes special treatment for a small set of very
commonly used type symbols (26 to be exact); for these types it
doesn't bother to emit type descriptors for "normal" compilations, and
instead only generates them for the runtime package, so as to reduce
object file bloat.

This patch moves the set of type symbols in question from the
PkgIdxNone index space (in the object file) to the PkgIdxBuiltin
space, which saves some work in the compiler and loader (reduces each
package's index space slightly).
