Disable the instantiation-depth-default.cpp test on NetBSD since it
requires more stack space than we have by default on NetBSD.
Differential Revision: https://reviews.llvm.org/D71419
// increases our per-frame stack usage enough that this test no longer fits
// within our normal stack space allocation.
// UNSUPPORTED: asan
+//
+// The default stack size on NetBSD is too small for this test.
