David Crawshaw 5aa5db7593 cmd/compile: use bufio.Reader directly in lexer
Removes an intermediate layer of functions that was clogging up a
corner of the compiler's profile graph.

I can't measure a performance improvement running a large build
like jujud, but the profile reports less total time spent in
gc.(*lexer).getr.
