    cmd/compile: handle pragmas immediately with -newparser=1 · ee161e85
    Matthew Dempsky authored
    Instead of saving all pragmas and processing them after parsing is
    finished, process them immediately during scanning like the current
    lexer does.
    
    This is a bit unfortunate because it means we can't use
    syntax.ParseFile to concurrently parse files yet, but it fixes how we
    report syntax errors in the presence of //line pragmas.
    
    While here, add a bunch more gcCompat entries to syntax/parser.go to
    get "go build -toolexec='toolstash -cmp' std cmd" passing. There are
    still a few remaining cases only triggered building unit tests, but
    this seems like a nice checkpoint.
