[pushed] c++: Add fixed test [PR91506]

[Marek Polacek via Gcc-patches]

Pre-r11-557 we issued a bogus

  error: parameter may not have variably modified type 'double [x]'

but now we compile this, as we should.

Tested x86_64-pc-linux-gnu, applying to trunk.

        * g++.dg/init/array60.C: New test.
