Use NodeName and Namespace in CSS JIT
https://bugs.webkit.org/show_bug.cgi?id=267671
rdar://121167170
Reviewed by Ryosuke Niwa and Justin Michaud.
1. Use NodeName in CSS JIT code generation. This is more efficient and we can
reduce code size.
2. Drop Darwin ARMv7 CSS JIT since it is no longer used.
3. We adjust registers so that this patch removes weird configuration of
Assemblers in CSS JIT (what registers are reserved etc.).
