Fix escape sequences in lexer: the capital X is not an EscapeCharacter.

The ECMA test suite has a test to check that none of the characters in
the English capital alphabet are escapable (S7.8.4_A4.2_T1). Or, put
differently, paragraph 7.8.4 states that only the lower-case x is
escapable and usable for a HexEscapeSequence.
