[clang-format] [PR36294] AlwaysBreakAfterReturnType works incorrectly
for some operator functions
Summary: https://bugs.llvm.org/show_bug.cgi?id=36294
Addressing bug related to returning after return type not being honoured
for some operator types.
```
$ bin/clang-format --style="{BasedOnStyle: llvm,
AlwaysBreakAfterReturnType: TopLevelDefinitions}" /tmp/foo.cpp class Foo
{ public:
 bool operator!() const;
 bool operator<(Foo const &) const;
 bool operator*() const;
 bool operator->() const;
 bool operator+() const;
 bool operator-() const;
 bool f() const;
};
bool Foo::operator!() const { return true; } bool Foo::operator<(Foo
const &) const {
 return true;
} bool Foo::operator*() const { return true; } bool Foo::operator->()
const { return true; } bool Foo::operator+() const {
 return true;
} bool Foo::operator-() const {
 return true;
} bool Foo::f() const {
 return true;
}

DWARFDebugLoclists: add location list "interpretation" logic
Summary: This patch extracts the logic for computing the "absolute"
locations, which was partially present in the debug_loclists dumper,
completes it, and moves it into a separate function. This makes it
possible to later reuse the same logic for uses other than dumping.
The dumper is changed to reuse the location list interpreter, and its 
format is changed somewhat. In "verbose" mode it prints the "raw" value 
of a location list, the interpreted location (if available) and the 
expression itself. In non-verbose mode it prints only one of the 
location forms: it prefers the interpreted form, but falls back to the
"raw" format if interpretation is not possible (for instance, because we 
were not given a base address, or the resolution of indirect addresses 
failed).
This patch also undos some of the changes made in D69672, namely the 
part about making all functions static. The main reason for this is that 
I learned that the original approach (dumping only fully resolved 
locations) meant that it was impossible to rewrite one of the existing 
tests. To make that possible (and make the "inline location" dump work 
in more cases), I now reuse the same dumping mechanism as is used for 
section-based dumping. As this required having more objects know about 
the various location lists classes, it seemed like a good idea to create 
an interface abstracting the difference between them.
Therefore, I now create a DWARFLocationTable class, which will serve as 
a base class for the location list classes. DWARFDebugLoclists is made 
to inherit from that. DWARFDebugLoc will follow.
Another positive effect of this change is that section-based dumping 
code will not need to use templates (as originally) envisioned, and that 
the argument lists of the dumping functions become shorter.

[lldb][NFC] Simplify a return in
ThreadPlanStepInRange::DefaultShouldStopHereCallback
We know should_stop_here is false here, so we might as well return false
directly.

[LoopInterchange] Only skip PHIs with incoming values from the inner
loop.
Currently we have limited support for outer loops with multiple basic 
blocks after the inner loop exit. But the current checks for creating 
PHIs for loop exit values only assumes the header and latches of the 
outer loop. It is better to just skip incoming values defined in the 
original inner loops. Those are handled earlier.

[InstCombine] Skip scalable vectors in combineLoadToOperationType
Don't try to canonicalize loads to scalable vector types to loads of
integers.
This removes one assertion when trying to use a TypeSize as a parameter 
to DataLayout::isLegalInteger. It does not handle the second part of the 
function (which looks at bitcasts).
This patch also contains a NFC fix for Load Analysis, where a variable 
initialization that would cause the same assertion is moved closer to 
its use. This allows us to run the new test for InstCombine without 
having to teach LocationSize to play nicely with scalable vectors.
