Right now, if we want to dump symbol at specified offset, we need to use `grep`.
And it can only show surrounding symbols in layout (not in lexical scope sense).
This adds similar options to `dump` command as `llvm-dwarfdump` to allow users
to dump symbol record at specified offset and its parents or children with
spcified depth.
`--symbol-offset=` must be used with `--modi` to dump only one symbol at given
offset.
`--show-parents`/`--show-children` must be used with `--symbol-offset` to
dump all symbols that are parents/children of the symbol at given offset.
`--parent-recurse-depth`/`--children-recurse-depth` must be used with
`--show-parents`/`--show-children` to specify the max up/down depth.

The change described by:
https://reviews.llvm.org/D122226
Moved some llvm-pdbutil functionality to the debug PDB library.
This patch addresses a broken '-modi' argument handling, which
causes an assertion if its value is other than '0' or '1'.
In addition, it moves the assertion for the number of occurrences
of the '-modi' argument from the PDB library into the llvm-pdbutil
driver.

Moved some llvm-pdbutil functionality to the debug PDB library.
This patch addresses one outstanding issue concerning the global
state (Filters) created in the PDB library.
- Move 'Filters' inside the 'LinePrinter' class.
- Omit 'Optional' and just pass 'PrintScope &HeaderScope' everywhere.

At Sony we are developing llvm-dva
https://lists.llvm.org/pipermail/llvm-dev/2020-August/144174.html
For its PDB support, it requires functionality already present in
llvm-pdbutil.
We intend to move that functionaly into the PDB library to be
shared by both tools. That change will be done in 2 steps, that
will be submitted as 2 patches:
(1) Replace 'ExitOnError' with explicit error handling.
(2) Move the intended shared code to the PDB library.
Patch for step (1): https://reviews.llvm.org/D121801
This patch is for step (2).
Move InputFile.cpp[h], FormatUtil.cpp[h] and LinePrinter.cpp[h]
files to the debug PDB library.
It exposes the following functionality that can be used by tools:
- Open a PDB file.
- Get module debug stream.
- Traverse module sections.
- Traverse module subsections.
Most of the needed functionality is in InputFile, but there are
dependencies from LinePrinter and FormatUtil.
Some other functionality is in the following functions in
DumpOutputStyle.cpp file:
- iterateModuleSubsections
- getModuleDebugStream
- iterateOneModule
- iterateSymbolGroups
- iterateModuleSubsections
Only these specific functions from DumpOutputStyle are moved to
the PDB library.
