Work around a stepping bug in arm64 android M
Summary:
On arm64, linux<=4.4 and Android<=M there is a bug, which prevents single-stepping from working when
the system comes back from suspend, because of incorrectly initialized CPUs. This did not really
affect Android<M, because it did not use software suspend, but it is a problem for M, which uses
suspend (doze) quite extensively. Fortunately, it seems that the first CPU is not affected by
this bug, so this commit implements a workaround by forcing the inferior to execute on the first
cpu whenever we are doing single stepping.
While inside, I have moved the implementations of Resume() and SingleStep() to the thread class
(instead of process).

Fixed a problem where the DWARF for inline functions was mis-parsed.
Inline functions in DWARF have AT_abstract_origin set, but we only handled that
if the functions were C++ methods. Inline functions -- C or C++ -- have this
also, and as a result they got one FunctionDecl for each inlined instance. When
going to construct the locals, this meant that the arguments (which did properly
have their abstract origins handled) would get associated with the master
FunctionDecl, and the inlined FunctionDecls would all appear to have no locals.
This manifested as not being able to look up local variables when stopped in an
inline fuunction. We should have had a test for this, but somewhere along the
line the relevant test case lost its .py file (or it never had one).
This patch fixes this problem and restores the .py file.

[LoopUnroll] Avoid unnecessary DT recomputation.
Summary:
When we completely unroll a loop, it's pretty easy to update DT in-place and
thus avoid rebuilding it. DT recalculation is one of the most time-consuming
tasks in loop-unroll, so avoiding it at least in case of full unroll should be
beneficial.
On some extreme (but still real-world) tests this patch improves compile time by
~2x.

[PM] Improve the API and comments around the analysis manager proxies.
These are really handles that ensure the analyses get cleared at
appropriate places, and as such copying doesn't really make sense.
Instead, they should look more like unique ownership objects. Make that
the case.
Relatedly, if you create a temporary of one and move out of it
its destructor shouldn't actually clear anything. I don't think there is
any code that can trigger this currently, but it seems like a more
robust implementation.
If folks want, I can add a unittest that forces this to be exercised,
but that seems somewhat pointless -- whether a temporary is ever created
in the innards of AnalysisManager is not really something we should be
adding a reliance on, but I didn't want to leave a timebomb in the code
here.
If anyone has a cleaner way to represent this, I'm all ears, but
I wanted to assure myself that this wasn't in fact responsible for
another bug I'm chasing down (it wasn't) and figured I'd commit that.
