When we moved to argparse command parsing we introduced `gdb_sloppy_parse` which wasn't perfect: e.g. for `gdb.parse_and_eval("__libc_start_main")` would return a `gdb.Value()` whose `.type.name` was `long long`.
As a result when code that used `gdb_sloppy_parse` then casted the result to `int(gdb_value)` it crashed because for some reason GDB errored.
This commit fixes the issues related to it by adding `AddressExpr` and `HexOrAddressExpr` functions.
It also adds tests for some of the windbg compatibility commands and fixes some nifty details here and there.
