Use ICU to check ID_Start, ID_Continue and WhiteSpace even for BMP
when V8_INTL_SUPPORT is on (which is default).
Change LineTerminator::Is() to check 4 code points from
ES#sec-line-terminators instead of using tables and Lookup function.
Remove Lowercase::Is(). It's not used anywhere.
Update webkit/{ToNumber,parseFloat}.js to have the correct expectation
for U+180E and the corresponding expected files. This is a follow-up to
an earlier change ( https://codereview.chromium.org/2720953003 ).
