[PATCH] Fix fast track of ios_read_uint

[egeyar]

Hello,

The attached patch fixes the fast track of the ios_read_uint and adds test cases to cover the fast track as well.

The cases of aligned 16 bits for both endianness are already tested in maps-uint-1.pk and maps-uint-2.pk. Therefore, this patch skips them and adds cases for all other aligned 8k bits up to 64. 

The proposed ChangeLog is:

        * testsuite/poke.map/maps-uint-41.pk: New test.
        * testsuite/poke.map/maps-uint-42.pk: Likewise.
        * testsuite/poke.map/maps-uint-43.pk: Likewise.
        * testsuite/poke.map/maps-uint-44.pk: Likewise.
        * testsuite/poke.map/maps-uint-45.pk: Likewise.
        * testsuite/poke.map/maps-uint-46.pk: Likewise.
        * testsuite/poke.map/maps-uint-47.pk: Likewise.
        * testsuite/poke.map/maps-uint-48.pk: Likewise.
        * testsuite/poke.map/maps-uint-49.pk: Likewise.
        * testsuite/poke.map/maps-uint-50.pk: Likewise.

Please take a look and apply if legitimate.
