Igor Kudrin d25e572421 [llvm-objdump] Print memory operand addresses as regular comments
The patch reuses the common code to print memory operand addresses as
instruction comments. This helps to align the comments and enables using
target-specific comment markers when `evaluateMemoryOperandAddress()` is
implemented for them.
