Pavel Labath 4446487d71 Improve LLDB prompt handling
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.

Tamas Berghammer 3afb2527ce Parse function name from DWARF DW_AT_abstract_origin
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.

Chandler Carruth 0ac95426ba [PM] Use a simpler technique to drop optional analysis manager arguments
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.

Tobias Grosser 7c3bad52dd Use value semantics for list of ScopStmt(s) instead of std::owningptr
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.

Enrico Granata e87764f247 Add support for custom commands to set flags on themselves
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

Chandler Carruth a004f22a2d [inliner] Fix the early-exit of the inline cost analysis to correctly
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.

David Majnemer 34568bc602 [MS ABI, DebugInfo] Omit the size for model-less pointers-to-members
The representation of a pointer-to-member in the MS ABI is governed by
the layout of the relevant class or if a model has been explicitly
specified.  If no model is specified, then an appropriate
"worst-case-scenario" model is implicitly chosen if, and only, if the
pointer-to-member type's representation was needed.

Debug info cannot force a pointer-to-member type to have a
representation so do not try to query the size of such a type unless we
know it is safe to do so.
