TODO: Remove the go.mod/go.sum in internal/tools once doing so doesn't break CI (e.g. once we drop support for go 1.19) * builder/cc1as.h: fix typo found by 'make spell' * GNUmakefile: remove exception for inbetween, fix instance now found by 'make spell' * GNUmakefile: remove exception for programmmer, fix instance now found by 'make spell' * go.mod: use updated misspell. GNUmakefile: add spellfix target, use it. * ignore directories properly when invoking spellchecker. * make spell: give internal/tools its own go.mod, as misspell requires newer go * make lint: depend on tools and run the installed revive (which was perhaps implied by the change that added revive to internal/tools, but not required in GNUmakefile until we gave internal/tools its own temporary go.mod) * .github: now that 'make spell' works well, run it from CI * GNUmakefile: make spell now aborts if it finds misspelt words, so what it finds doesn't get lost in CI logs * GNUmakefile: tools: avoid -C option on go generate to make test-llvm15-go119 circleci job happy, see https://cs.opensource.google/go/go/+/2af48cbb7d85e5fdc635e75b99f949010c607786 * internal/tools/go.mod: fix format of go version to leave out patchlevel, else go complains.

// This implementation of crypto/rand uses the arc4random_buf function

// Note: arc4random_buf (unlike what the name suggests) does not use the insecure

// RC4 cipher. Instead, it uses a high-quality cipher, varying by the libc
