Use eAddressClassCode for address lookup for opcodes for stack frames

Browse Source 
It is required because of the following edge case on arm:

bx <addr>   Non-tail call in a no return function
[data-pool] Marked with $d mapping symbol

The return address of the function call will point to the data pool but
we have to treat it as code so the StackFrame can calculate the symbols
correctly.
