cmd/go: do not index std as a module in modcache We do not index std as a whole module ever. When working in the main Go repo, files in package change often, so we don't want to pay the cost of reindexing all of std when what we really need is just to reindex strings. Per-package indexing works better for that case. When using a released Go toolchain, we don't have to worry about the whole module changing, but if we switch to whole-module indexing at that point, we have the potential for bugs that only happen in released toolchains. Probably not worth the risk. For similar reasons, we don't index the current work module as a whole module (individual packages are changing), so we use the heuristic that we only do whole-module indexing in the module cache. The new toolchain modules live in the module cache, though, and our heuristic was causing whole-module indexing for them. As predicted, enabling whole-module indexing for std when it's completely untested does in fact lead to bugs (a very minor one). This CL turns off whole-module indexing for std even when it is in the module cache, to bring toolchain module behavior back in line with the other ways to run toolchains. For #57001.
