ada: Avoid temporary for conditional expression of discriminated record type
This just aligns the definite case (discriminants with default) with the
indefinite case (discriminants without default), the latter case having
been properly handled for long. In the former case, the maximum size is
used so a temporary can be much larger than the actual data it contains.
gcc/ada/
* gcc-interface/utils2.cc (build_cond_expr): Use the indirect path
for all types containing a placeholder.
