[Ada] Remove misleading warning/suggestion in membership test
This patch removes a warning on a membership test whose right operand is
given by a range. In many cases the check can be replaced by the use of
attribute 'Valid, but if the bounds of range are type conversion this
replacement would be invorrect and the warning and suggestion are
misleading.

* exp_ch4.adb (Expand_N_In): Do not suggest the use of attribute
'Valid as a replacement for a range check on a discrete type
when the bounds of the range are given by type conversions,
because in such a case there are distinct types involved and the
subbested attribute replacement would be misplaced.

* gnat.dg/warn26.adb: New testcase.
