[Assignment Tracking] Fix fragments for assignments to variables smaller than the alloca
Prior to this patch the trackAssignments function would attribute all stores to
an alloca to all variables linked to the alloca. This is wrong in the case
where the alloca contains variables which are smaller than the alloca, and
caused erroneous fragment information to be generated.
Now stores outside the variable bounds are discarded, and we check whether a
fragment is needed based on whether the store covers the entire variable as
opposed to whether it covers the entire alloca (except for variables of unknown
size).
Note that trackAssignments doesn't yet understand whole variables sitting at
anything other than offset 0 in an alloca - those variables are still tracked
using dbg.declares.

[-Wunsafe-buffer-usage] FixableGadget for handling stand alone pointers under UPC
This patch introduces UPCStandalonePointerGadget, a FixableGadget that emits fixits to
handle cases where a pointer identified as unsafe is simply referenced. An example of
such a case is when the pointer is input as an argument to a method call, where we can
not change the type of the argument. For cases where the strategy for the unsafe pointer is
to use std::span, the idea is to extract the underlying pointer by invoking the "data()"
method on the span instance.
For example, the gadget emits a fixit for S3, where S1, S2 are handled by other gadgets:
S1: int *ptr = new int[10];
S2: int val1 = ptr[k]; // Unsafe operation on ptr
S3: foo(ptr); // Some method that accepts raw pointer => FIXIT: foo(ptr.data());

[Sanitizers][Atos] Remove null-ing of atos process pointer
Currently, when we send an address to atos to be symbolized, it is
expected that atos returns with more than it was sent, i.e. symbol
information for that address. In the case where only the address is
returned, we currently null the pointer to the atos process. Typically,
for modules where no symbolication is expected, we do not send the
address to atos.
However, in new simulators there is an early call that atos does not
return any symbol information for. And in this case, because we have
gotten rid of the pointer to the process, no subsequent frames are
symbolicated, even tho atos is still working/running.
This patch removes the nulling of the pointer to the process. This
allows subsequent calls to atos even after an unexpected result.
It also now Reports what has happened and the address this occurred.
This will improve symbolication in cases where we get an unepxected
result, and will make it easier to diagnose atos if it is not
symbolicating as expected.

[lldb] Move "SelectMostRelevantFrame" from Thread::WillStop
SelectMostRelevantFrame triggers the StackFrameRecognizer construction,
which can run arbitrary Python code, call expressions etc. WillStop gets
called on every private stop while the recognizers are a user-facing
feature, so first off doing this work on every stop is inefficient. But
more importantly, you can get in to situations where the recognizer
causes an expression to get run, then when we fetch the stop event at
the end of the expression evaluation, we call WillStop again on the
expression handling thread, which will do the same StackFrameRecognizer
work again. If anyone is locking along that path, you will end up with a
deadlock between the two threads.
The example that brought this to my attention was the
objc_exception_throw recognizer which can cause the objc runtime
introspection functions to get run, and those take a lock in
AppleObjCRuntimeV2::DynamicClassInfoExtractor::UpdateISAToDescriptorMap
along this path, so the second thread servicing the expression deadlocks
against the first thread waiting for the expression to complete.
It makes more sense to have the frame recognizers run on demand, either
when someone asks for the variables for the frame, or when someone does
GetSelectedFrame. The former already worked that way, the only reason
this was being done in WillStop was because the StackFrameRecognizers
can change the SelectedFrame, so you needed to run them before the
anyone requested the SelectedFrame.
This patch moves SelectMostRelevantFrame to StackFrameList, and runs it
when GetSelectedFrame is called for the first time on a given stop. If
you call SetSelectedFrame before GetSelectedFrame, then you should NOT
run the recognizer & change the frame out from under you. This patch
also makes that work. There were already tests for this behavior, and
for the feature that caused the hang, but the hang is racy, and it
doesn't trigger all the time, so I don't have a way to test that
explicitly.
One more detail: it's actually pretty easy to end up calling
GetSelectedFrame, for instance if you ask for the best ExecutionContext
from an ExecutionContextRef it will fill the StackFrame with the result
of GetSelectedFrame and that would still have the same problems if this
happens on the Private State Thread. So this patch also short-circuits
SelectMostRelevantFrame if run on the that thread. I can't think of any
reason the computations that go on on the Private State Thread would
actually want the SelectedFrame - that's a user-facing concept, so
avoiding that complication is the best way to go.

[flang] Handle correctly user defined assignment for allocatable component
In the Fortran standard 2018 section 10.2.1.3 (13), it is mentioned
that all noncoarray allocatable component must follow this sequence of
operations:
1) If the component of the variable is allocated, it is deallocated.
2) If the component of the value of expr is allocated, the corresponding
component of the variable is allocated with the same dynamic type and
type parameters as the component of the value of expr. If it is an
array, it is allocated with the same bounds. The value of the
component of the value of expr is then assigned to the corresponding
component of the variable using defined assignment if the declared type
of the component has a type-bound defined assignment consistent with the
component, and intrinsic assignment for the dynamic type of that component
otherwise.
This patch updates the code to make use of the user defined assignment for
allocatable component and make sure the component is allocated correctly.
