Pull request #377 (2023-03-06 03:40:55)

all: remove +build tags
Commit 759be3dad9ef628049c42ef41326d5357618fb32 bumped our Go requirement to 1.18 which allows us to drop support for old-style `+build` tags. This change runs `go fix ./...` to remove them, and updates some remaining code generators that produced `+build` lines.
