Add local to/from operand helpers similar to argument to/from operand2
https://bugs.webkit.org/show_bug.cgi?id=121056
Reviewed by Geoffrey Garen.
Added localToOperand(), operandToLocal() and operandIsLocal() to Operands.h, very similar to
argumentToOperand(), et al. Used the new helpers everywhere where an index into a data
structure is intended instead of the actual virtual register offset. When the stack is
changed to grow down, local register offsets can be negative. Also added the helper
DFG::SpeculativeJIT::generationInfoFromVirtualRegister() for the common case accessing
m_generationInfo[operandToLocal(val)].
