Some JSValue cleanup
​https://bugs.webkit.org/show_bug.cgi?id=69320

../JavaScriptCore:

Reviewed by Darin Adler.

No measurable performance change.

Removed some JSValue::get* functions. get* used to be an optimization
when every value operation was a virtual function call: get* would combine
two virtual calls into one. Now, with non-virtual, inlined functions, get*
isn't faster, and may be slightly slower.

Merged getBoolean(bool&) and getBoolean() into asBoolean().

Merged uncheckedGetNumber(), getJSNumber() and getNumber() into
asNumber().
