Extends DWARF expression larguage to express locals/globals locations. (via
target-index operands atm) (possible variants are: non-virtual registers
or address spaces)

The WebAssemblyExplicitLocals can replace virtual registers to targer-index operand type at the time when WebAssembly backend introduces {get,set,tee}_local instead of
corresponding virtual registers.
