[lldb] Fix RangeDataVector::CombineConsecutiveEntriesWithEqualData (#127059)
Function was merging equal data even if they weren't adjecant. This
caused a problem in command-disassemble.s test because the two ranges
describing the function would be merged and "swallow" the function
between them.

This PR copies/adapts the algorithm from
RangeVector::CombineConsecutiveEntries (which does not have the same
problem) and also adds a call to ComputeUpperBounds as moving entries
around invalidates the binary tree. (The lack of this call wasn't
noticed until now either because we were not calling methods which rely
on upper bounds (right now, it's only the ill-named FindEntryIndexes
method), or because we weren't merging anything.

[lldb] Store *signed* ranges in lldb_private::Block (#120224)
This is to support functions whose entry points aren't their lowest
address

(https://discourse.llvm.org/t/rfcish-support-for-discontinuous-functions/83244).
The alternative is to keep blocks relative to the lowest address, but
then introduce a separate concept for the function entry point, which I
think would be more confusing.

This patch just changes the type signedness, it doesn't create any
negative offsets yet. Since combining values with different signs can
sometimes produce unexpected results, and since this is the first use of
RangeVector with a signed type, I'm adding a test to verify that at
least the core functionality works correctly.

81d7ebaf5c [lldb/Utility] Fix a bug in RangeMap::CombineConsecutiveRanges
The function didn't combine a large entry which overlapped several other
entries, if those other entries were not overlapping among each other.

E.g., (0,20),(5,6),(10,11) produced (0,20),(10,11)

Now it just produced (0,20).

808142876c [lldb][NFC] Fix all formatting errors in .cpp file headers
Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).

This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

2f2f41e12c RangeDataVector: Support custom sorting for D63540
As suggested by @labath extended RangeDataVector so that user can provide
custom sorting of the Entry's `data' field for D63540.
        https://reviews.llvm.org/D63540

RangeData functions were used just by RangeDataVector (=after I removed them
LLDB still builds fine) which no longer uses them so I removed them.
