[COMMITTED] ada: Accept aggregates with OTHERS clause in unchecked type conversions

[Marc Poulhiès]

From: Piotr Trojanek <trojanek@adacore.com>

When inlining subprogram calls in GNATprove mode, the actual parameter
is wrapped in an unchecked conversion. If this actual parameter is an
aggregate OTHERS clause, then the type of unchecked conversion allows us
to resolve this clause (just like for aggregates wrapped in a qualified
expression).

Previously such aggregates were rejected, which caused spurious and
cryptic errors; now they are accepted.

gcc/ada/

	* sem_aggr.adb (Resolve_Aggregate): Accept aggregates with OTHERS
	appearing inside unchecked conversions.

Tested on x86_64-pc-linux-gnu, committed on master.
