Test 0366_0074 accesses data from the common block both through common block and dummy arguments

[ashermancinelli]

I see two aliasing issues here:

First issue:

• test1 declares common/com/dummy,a
• inline1 declares common/com/b,dummy (different order)
• The array a is passed as an argument to inline1
• Inside inline1, in the statement a(i) = b(i) + 1, a and b are both referencing the same memory location through different paths (dummy argument and common block)

Second issue:

• Module moda uses equivalence(x,y(2)), making x overlap with y starting at y(2)
• test2 uses x as a and passes it to inline2
• inline2 uses y as b and performs a(i) = b(i) + 1, with a and b reference overlapping memory regions

This causes all of these compilers to give different answers when optimizations are enabled:

This looks similar to #10. CC @eugeneepshteyn
