Normalize newlines in Comment::getReformattedText()

Normalize CRLF to LF in getReformattedText(). That was, if the
comment is pretty-printed, we will use proper LF newlines, rather
than inserting indentation between the CR and LF.

At the same time, this also makes it easier to emit actual CRLF
newlines with a custom pretty printer.

Fixes #599.

Fix emulative lexer with default error handler

If no error handler is provided, explicitly create one, so we don't

For types the use of a string is ambiguous -- it could be either
an Identifier or a Name. Don't guess.

an Identifier or a Name. Don't guess.

Retain the implicit promotion to Identifier in places where only
Identifier is legal, e.g. various symbol names.

Treat del as label character depending on PHP version

In formatting-preserving pretty printing, treat DEL as a label
character based on the target PHP version (the default of 7.1
implying it isn't one).

This avoids failure to round-trip an unchanged input.
