This is an extension of https://go-review.googlesource.com/c/31662/ to mark all the temporaries, not just the ssa-generated ones. Before-and-after ls -l `go tool -n compile` shows a 3% reduction in size (or rather, a prior 3% inflation for failing to filter temps out properly.) Replaced name-dependent "is it a temp?" tests with calls to *Node.IsAutoTmp(), which depends on AutoTemp. Also replace calls to istemp(n) with n.IsAutoTmp(), to reduce duplication and clean up function name space. Generated temporaries now come with a "." prefix to avoid (apparently harmless) clashes with legal Go variable names. Fixes #17644. Fixes #17240.
