tryAddingSymbolicOperand - trys to add a symbolic operand in place of the immediate Value in the MCInst.

Parameters
Value- The immediate Value, has had any PC adjustment made by the caller.
isBranch- If the instruction is a branch instruction
Address- The starting address of the instruction
Offset- The byte offset to this immediate in the instruction
Width- The byte width of this immediate in the instruction

If the getOpInfo() function was set when setupForSymbolicDisassembly() was called then that function is called to get any symbolic information for the immediate in the instruction using the Address, Offset and Width. If that returns non-zero then the symbolic information it returns is used to create an MCExpr and that is added as an operand to the MCInst. If getOpInfo() returns zero and isBranch is true then a symbol look up for immediate Value is done and if a symbol is found an MCExpr is created with that, else an MCExpr with the immediate Value is created. This function returns true if it adds an operand to the MCInst and false otherwise.
