  Log Message:
  -----------
  Add tests to verify behavior of .cfi_sections .debug_frame intrinsic.

There was some lacking test coverage for checking when the
.cfi_sections .debug_frame intrinsic is emitted. On x86_64,
with -fno-exceptions there is no .cfi_sections .debug_frame intrinsic
emitted because there is an unwind table attribute.

On AArch64, with -fno-exceptions, there is no unwind table attribute, so
the .cfi_sections .debug_frame intrinsic is emitted correctly.

Alternatively, with -fexceptions, both AArch64 and x86_64 emit an unwind
table and therefore do not emit a .cfi_sections .debug_frame intrinsic

All this work was done in addition to https://reviews.llvm.org/D139663
patch.
