c++: Fix crash with broken deduction from {} [PR97895]
Unfortunately, the otherwise beautiful
for (constructor_elt &elt : *CONSTRUCTOR_ELTS (init))
is not immune to an empty constructor, so we have to check
CONSTRUCTOR_ELTS first.
gcc/cp/ChangeLog:
PR c++/97895
* pt.c (do_auto_deduction): Don't crash when the constructor has
zero elements.
gcc/testsuite/ChangeLog:
PR c++/97895
* g++.dg/cpp0x/auto54.C: New test.
