Reviewed by Anders Carlsson.

Source/WebCore:

* css/CSSGrammar.y.in: Use AtomicString::number instead of String::number since
we are creating an AtomicString. This can save a memory allocation if the string
happens to already be in the atomic string table.

(WebCore::Element::setIntegralAttribute): Ditto.
(WebCore::Element::setUnsignedIntegralAttribute): Ditto.
* editing/BreakBlockquoteCommand.cpp:
(WebCore::BreakBlockquoteCommand::doApply): Ditto.
* html/HTMLBodyElement.cpp:
(WebCore::HTMLBodyElement::insertedInto): Use setIntegralAttribute instead of
a local homegrown equivalent.

Source/WTF:

* wtf/text/AtomicString.cpp:
(WTF::AtomicString::number): Added.
* wtf/text/AtomicString.h: Ditto.

* wtf/text/IntegerToStringConversion.h: Simplify includes, renamed ConversionTrait to
IntegerToStringConversionTrait. Changed String version to use String since we no longer
need to use PassRefPtr to efficiently handle return values. Replaced UnsignedIntegerTrait
with std::make_unsigned. Added AtomicString support. Use nullptr instead of 0.
