Great solution to the bit shortage, just needs a bit of polish.

> Source/WebCore/css/CSSInitialValue.h:51
> +    bool m_isImplicit : 1;

No need for this to be a bitfield.

> Source/WebCore/css/CSSValue.h:161
> +        , m_valueListSeparator(CommaSeparator)

SpaceSeparator strikes me as a slightly more suitable default value here, since that would make all fields 0 in a newly constructed CSSValue.
The actual value doesn't matter anyway since all CSSValueList constructors overwrite it.

> Source/WebCore/css/CSSValue.h:184
> +    unsigned char m_valueListSeparator : ValueListSeparatorBits; // CSSValueList type

The "// CSSValueList type" comment adds nothing.

> Source/WebCore/css/CSSValueList.cpp:129
> -            if (isSpaceSeparated())

There's no need for this to be inside the loop. We can determine the right separator string beforehand and store it in a String.

> Source/WebCore/css/CSSValueList.h:45
> +    static PassRefPtr<CSSValueList> createSlashSeparated()
> +    {
> +        return adoptRef(new CSSValueList(SlashSeparator));
>      }

We shouldn't add a create*() method if we're not going to use it.

Unnecessary comment.
