Reviewed by Darin Adler.
Use move constructor instead of memcpy() for CSSSelector in the
CSSSelectorList constructor.
This tested as performance neutral on Speedometer.
It also reduces help get rid of one use of `WTF_ALLOW_UNSAFE_BUFFER_USAGE`.
* Source/WebCore/css/CSSSelector.h:
(WebCore::CSSSelector::CSSSelector):
Introduce move constructor.
(WebCore::CSSSelector::operator=):
Introduce corresponding move assignment operator for completeness but it
is not required at the moment.
(WebCore::CSSSelector::~CSSSelector):
Drop some unnecessary data member resetting in the destructor. The object
is being destroyed anyway.
* Source/WebCore/css/CSSSelectorList.cpp:
(WebCore::CSSSelectorList::CSSSelectorList):
Rely on new move constructor instead of memcpy().
