[PATCH,testsuite]Fix misc tests for AVR target

[Andy H <hutchinsonandy at aim dot com>]

Janis,

the attach patch fixes a whole bunch of tests for AVR and small targets
Some are fixed to account for different data sizes. Some are skipped.
Some are marked xfail.

Conversion warning checks are particulary awkward, as they are highly
dependent on data sizes.
Some additional AVR only  tests are added to cover extra warning due to
data sizes. to avoid excess error failures.
Where different warnings are emitted on AVR, test are skipped and excess
warning test are  marked xfail.

These have been tested on AVR target. Also on i686 - no regressions

Ok for mainline 4.4?
