John Naylor 0a8de93a48 Speed up lexing of long JSON strings
Use optimized linear search when looking ahead for end quotes,
backslashes, and non-printable characters. This results in nearly 40%
faster JSON parsing on x86-64 when most values are long strings, and
all platforms should see some improvement.
