These tests are located in 'X86' subfolders which means that they should
be compiled for that target. As they did not have the target specified
explicitly, they in fact were compiled for a default target triple. Not
all targets support all required features for these tests; for example,
if NVPTX is used as a default triple, the tests fail. The patch makes the
tests run for 'x86_64', thus they pass regardless of the default target.

This is needed to support fortran assumed rank arrays which
have runtime rank.
Summary:
Fortran assumed rank arrays have dynamic rank. DWARF TAG
DW_TAG_generic_subrange is needed to support that.
Testing:
