VirtualRegister should be a class
https://bugs.webkit.org/show_bug.cgi?id=121732
Reviewed by Geoffrey Garen.
This is a refactoring change. Changed VirtualRegister from an enum to a class.
Moved Operands::operandIsArgument(), operandToArgument(), argumentToOperand()
and the similar functions for locals to VirtualRegister class.
This is in preparation for changing the offset for the first local register from
0 to -1. This is needed since most native calling conventions have the architected
frame pointer (e.g. %rbp for X86) point at the slot that stores the previous frame
pointer. Local values start below that address.
