Pavel Labath 7ed3e22f00 [unittests] Add a helper function for getting an input file
Summary:
Fetching an input file required about five lines of code, and this was
repeated in multiple unit tests, with slight variations. Add a helper
function for doing that into the lldbUtilityMocks module (which I rename
to lldbUtilityHelpers to commemorate the fact it includes more than
mocks)

Pavel Labath 3f2a08183f [DWARFCallFrameInfo] Add Type enum to differentiate eh/debug_frame sections
Summary:
instead of using a boolean to differentiate between the two section
types, use an enum to make the intent clearer.

I also remove the RegisterKind argument from the constructor, as this
can be deduced from the Type argument.

Pavel Labath cdda23eb7c Add debug_frame section support
Summary:
This is a beefed-up version of D33504, which adds support for dwarf 4
debug_frame section format.

The main difference here is that the decision whether to use eh_frame or
debug_frame is done on a per-function basis instead of per-object file.
This is necessary because one module can contain both sections (for
example, the start files added by the linker will typically pull in
eh_frame), but we want to be able to access both, for maximum
information.

I also add unit test for parsing various CFI formats (eh_frame,
debug_frame v3 and debug_frame v4).
