George Rimar e3fb2d549b Recommit r369190 "[llvm-readobj/llvm-readelf] - Improve/cleanup the error reporting API."
Fix: Add a `consumeError` call removed by mistake to 'printStackSize',
this should fix the "Expected<T> must be checked before access or destruction." reported by following bot:
http://lab.llvm.org:8011/builders/clang-x64-windows-msvc/builds/9743/steps/stage%201%20check/logs/stdio

Original commit message:
Currently we have the following functions for error reporting:

LLVM_ATTRIBUTE_NORETURN void reportError(Twine Msg);
void reportError(Error Err, StringRef Input); 
void reportWarning(Twine Msg);
void reportWarning(StringRef Input, Error Err);
void warn(llvm::Error Err);
void error(std::error_code EC);

Problems are: naming is inconsistent, arguments order is inconsistent,
some of the functions looks excessive.

After applying this patch we have:

void reportError(Error Err, StringRef Input); 
void reportError(std::error_code EC, StringRef Input);
void reportWarning(Error Err, StringRef Input);

I'd be happy to remove reportError(std::error_code EC, StringRef Input) too, but it
is used by COFF heavily.

Test cases were updated, they show an improvement introduced.

Fangrui Song 677423997d [llvm-readobj] Allow --hex-dump/--string-dump to dump multiple sections
1) `-x foo` currently dumps one `foo`. This change makes it dump all `foo`.
2) `-x foo -x foo` currently dumps `foo` twice. This change makes it dump `foo` once.
   In addition, if foo has section index 9, `-x foo -x 9` dumps `foo` once.
3) Give a warning instead of an error if `foo` does not exist.

The new behaviors match GNU readelf.

Also, print a new line as a separator between two section dumps.
GNU readelf uses two lines, but one seems good enough.

Stephen Tozer 19bb1d5739 [llvm-readobj] Reapply: Improve error message for --string-dump
This is a resubmission of a previous patch that caused test failures,
with the fixes for the relevant tests included.

Fixes bug 40630: https://bugs.llvm.org/show_bug.cgi?id=40630

This patch changes the error message when the section specified by
--string-dump cannot be found by including the name of the section in
the error message and changing the prefix text to not imply that the
file itself was invalid. As part of this change some uses of
std::error_code have been replaced with the llvm Error class to better
encapsulate the error info (rather than passing File strings around),
and the WithColor class replaces string literal error prefixes.

James Henderson 416603e32a [llvm-readobj]Add additional testing for various ELF features
This patch adds testing of areas of the code that are not fully tested,
in particular dynamic table printing, ELF type printing, handling of
edge cases where things are missing/empty (relocations/program header
tables/section header table), and the --string-dump switch.
