In ProcessGDBRemote we currently have a single packet, m_last_stop_packet, used to set the thread stop info.
However in non-stop mode we can receive several stop reply packets in a sequence for different threads. As a result we need to use a container to hold them before they are processed.
This patch also changes the return type of CheckPacket() so we can detect async notification packets.

Avoiding ugly combination of string parsing in the front-end. We still
need to move away from CPU parsing at all, but that's for a different
commit.

Summary:
There is an issue in lldb where the command prompt can appear at the wrong time. The partial fix
we have in for this is not working all the time and is introducing unnecessary delays. This
change does:
- Change Process:SyncIOHandler to use integer start id's for synchronization to avoid it being
confused by quick start-stop cycles. I picked this up from a suggested patch by Greg to
lldb-dev.
- coordinates printing of asynchronous text with the iohandlers. This is also based on a
(different) Greg's patch, but I have added stronger synchronization to it to avoid races.
Together, these changes solve the prompt problem for me on linux (both with and without libedit).
I think they should behave similarly on Mac and FreeBSD and I think they will not make matters
worse for windows.
Test Plan: Prompt comes out alright. All tests still pass on linux.

A DW_TAG_subprogram entry can contain a reference to a
DW_AT_abstract_origin entry instead of duplicating the information
from it (e.g.: name) when the same function is inlined in some case
and not inlined in other cases.
This CL fixes name parsing for the case when the DW_TAG_subprogram
for the non inlined version contains just a reference to the
DW_AT_abstract_origin entry instead of the full information.

I have no idea why, but compilers seem to hate this and its late, so I'm
not going to debug it. :: sigh :: This is why we can't have nice things.

when invoking run methods.
This technique was suggested by Dinesh Dwivedi who also wrote the
original patch. During the code review, they explained to me that this
isn't a fully general technique as we need to know the signatures of the
method candidates. Since this is really a narrower utility, I switched
the names and structure to be more clearly a specialized run method
invoke helper and commented it accordingly. I still think this is
a pretty big win.
Very sorry to Dinesh for the extreme delay in landing this patch. I've
been far to busy poking at other things.

We do not need to merge ELF flags from DSO. But `isCompatible` is called
for all input files. So this change move ELF flags merging into the
MipsELFFile class.

This broke the llvm-mips-linux builder and several of our out-of-tree builders.
Initial investigations show that the commit probably isn't the problem but
reverting anyway while I investigate.

David Blaikie:
"find returns an iterator by value, so it's just added complexity/strangeness to
then use reference lifetime extension to give it the same semantics as if you'd
used a value type instead of a reference type."

With this patch the x86 backend is now shrink-wrapping capable
and this functionality can be tested by using the
-enable-shrink-wrap switch.
The next step is to make more test and enable shrink-wrapping by
default for x86.

A definintion like this could not be formatted at all:

aa?: string,

aaaaaaaaaaaaaaa?: boolean,
aaaaaa?: List<string>
}) {

David Blaike suggested this as an alternative to the use of owningptr(s) for our
memory management, as value semantics allow to avoid the additional interface
complexity caused by owningptr while still providing similar memory consistency
guarantees. We could also have used a std::vector, but the use of std::vector
would yield possibly changing pointers which currently causes problems as for
example the memory accesses carry pointers to their parent statements. Such
pointers should not change.

- Clean documentation comment
- Change the API to accept an iterator so you can actually pass
MachineBasicBlock::end() now.
- Add more "const".

This works for Python commands defined via a class (implement get_flags on your class) and C++ plugin commands (which can call SBCommand::GetFlags()/SetFlags())
Flags allow features such as not letting the command run if there's no target, or if the process is not stopped, ...
Commands could always check for these things themselves, but having these accessible via flags makes custom commands more consistent with built-in ones

model the dense vector instruction bonuses.
Previously, this code really didn't effectively compute the density of
inlined vector instructions and apply the intended inliner bonus. It
would try to compute it repeatedly while analyzing the function and
didn't handle the case where future vector instructions would tip the
scales back towards the bonus.
Instead, speculatively apply all possible bonuses to the threshold
initially. Once we *know* that a certain bonus can not be applied,
subtract it. This should delay early bailout enough to get much more
consistent results without actually causing us to analyze huge swaths of
code. I expect some (hopefully mild) compile time hit here, and some
swings in performance, but this was definitely the intended behavior of
these bonuses.
This also dramatically simplifies the computation of the bonuses to not
interact with each other in confusing ways. The previous code didn't do
a good job of this and the values for bonuses may be surprising but are
at least now clearly written in the code.
Finally, fix code to be in line with comments and use zero as the
bailout condition.
Patch by Easwaran Raman, with some comment tweaks by me to try and
further clarify what is going on with this code.
