d: Missed RVO optimization with non-POD structs
The D front-end semantic pass sometimes declares a temporary inside a
return expression. This is now detected with the RESULT_DECL replacing
the temporary, allowing for RVO to be done.
PR d/101273
gcc/d/ChangeLog:
* toir.cc (IRVisitor::visit (ReturnStatement *)): Detect returns that
use a temporary, and replace with return value.
gcc/testsuite/ChangeLog:
* gdc.dg/torture/pr101273.d: New test.
