[Ada] Spurious warning on uninitialized entity during code generation
This patch suppresses a spurious warning coming from the GCC backend, on
an aggregate that cannot be built in place and for which a temporary
variable must be created. If the type of the aggregate is a packed
boolean array, the generated code may appear to use an uninitialized
value for a component of the array, when in fact the code simply sets a
single bit of that array.

gcc/ada/
* exp_aggr.adb (Expand_Array_Aggregate): If it is not possible
to build in place an aggregate with component associations, set
the Warnings_Off flag on the generated temporary, to prevent
spurious warnings from the backend when compiling with the
-Wuninitialized gcc flag.
gcc/testsuite/
* gnat.dg/warn18.adb: New testcase.
