4b26377660 DwarfDebug: Split the initialization of abstract and non-abstract subprogram DIEs.
These were called from distinct places and had significant distinct
behavior. No need to make that a dynamic check inside the function
rather than just having two functions (refactoring some common code into
a helper function to be called from the two separate functions).

d13e09a560 Remove DwarfUnit::LabelRange since it's unused.
Seems at some point the intent was to emit fission ranges_base as unique
per CU but the code today emits ranges_base as the start of the ranges
section for all CUs being compiled and all the ranges_base relative
addresses are relative to that. So removing this dead code and leaving
the status quo until there's a reason to change it (perhaps something's
faster if it has distinct ranges for each CU).

686bd64d0c Satisfy sub-optimal GCC warning.
(Clang doesn't warn here because it knows the string is benign - the
assert still checks what it's intended to - though putting the correct
parens does make clang-format format the code a little better)

9feea1a5a1 DebugInfo: Just store the DIE by value in the DwarfUnit
Since all 4 ctor calls in DwarfDebug just pass in a trivially
constructed DIE with the right tag type, sink the tag selection down
into the Dwarf*Unit ctors (removing the argument entirely from callers
in DwarfDebug) and initialize the DIE member in DwarfUnit.

7c17e94756 Improve explicit memory ownership of DIEs
Now that the subtle constructScopeDIE has been refactored into two
functions - one returning memory to take ownership of, one returning a
pointer to already owning memory - push unique_ptr through more APIs.

I think this completes most of the unique_ptr ownership of DIEs.

becd8e75b8 DwarfDebug: Omit DW_AT_object_pointer on inlined_subroutines
While refactoring out constructScopeDIE into two functions I realized we
were emitting DW_AT_object_pointer in the inlined subroutine when we
didn't need to (GCC doesn't, and the abstract subprogram definition has
the information already).

So here's the refactoring and the bug fix. This is one step of
refactoring to remove some subtle memory ownership semantics. It turns
out the original constructScopeDIE returned ownership in its return
value in some cases and not in others. The split into two functions now
separates those two semantics - further cleanup (unique_ptr, etc) will
follow.

4f18a81aba DWARF Type Units: Avoid emitting type units under fission if the type requires an address.
Since there's no way to ensure the type unit in the .dwo and the type

This implementation is a bit inefficient for a few reasons, called out
in comments.

f95477d11f DwarfDebug: Minor refactoring around type unit construction
Sinking addition of the declaration attribute down to where the
signature is added. So that if the signature is not added neither is the
declaration attribute (this will come in handy when aborting type unit
construction to instead emit the type into the CU directly in some
cases)

Pull out type unit identifier hashing just to simplify the function a
little, it'll be getting longer.

only one address table).

12d5224df6 DIE: Pass ownership of children via std::unique_ptr rather than raw pointer.
This should reduce the chance of memory leaks like those fixed in

Pushing unique_ptr and references through more APIs should help expose
the cases where ownership is a bit fuzzy.

875f90e527 Push memory ownership of DwarfUnits into clients of DwarfFile.
This prompted me to push references through most of DwarfDebug. Sorry
for the churn.

Honestly it's a bit silly that we're passing around units all over the
place like that anyway and I think it's mostly due to the DIE attribute
adding utility functions being utilities in DwarfUnit. I should have
another go at moving them out of DwarfUnit...
