-----------
[JSC] Add index() / setIndex() to DFG::BasicBlock
https://bugs.webkit.org/show_bug.cgi?id=317621
rdar://180352661
Reviewed by Dan Hecht.
Add DFG::BasicBlock::index() getter / setter and making index member to
m_index and make it private member field. This makes DFG::BasicBlock
more similar to B3::BasicBlock, which allows sharing code easily. We
would like to unify DFG::SSACalculator and B3::SSACalculator as they are
almost the same.
By doing so, now we can use IndexMap for both DFG and B3. Use IndexMap
and remove BlockMap.
