George Rimar 7915260853 [llvm-readobj/llvm-readelf] - .stack_sizes: demangle symbol names in warnings reported.
I started this patch as a refactoring, tried to make a helper for
getting symbol names, similar to how we get section names
used in warning messages.

So this patch cleanups the code and fixes an issue: symbol names
in warning messages were not demangled.

George Rimar 8ce581f586 [llvm-readobj] - Simplify stack-sizes.test test case.
This is a follow-up for D67757,
which allows to describe .stack_sizes sections with a new
YAML syntax.

George Rimar 5b9a408113 [llvm-readobj] - Don't crash when dumping .stack_sizes and unable to find a relocation resolver.
The crash might happen when we have either a broken or unsupported object
and trying to resolve relocations when dumping the .stack_sizes section.

For the test case I used a 32-bits ELF header and a 64-bit relocation.
In this case a null pointer is returned by the code instead of the relocation
resolver function and then we crash.

George Rimar 1a219aa8df [yaml2obj/obj2yaml] - Add support for .stack_sizes sections.
.stack_sizes is a SHT_PROGBITS section that contains pairs of
<address (4/8 bytes), stack size (uleb128)>.

This patch teach tools to parse and dump it.

George Rimar 753f6cff2f [llvm-readobj] - Stop treating ".stack_sizes.*" sections as stack sizes sections.
llvm-readobj currently handles .stack_sizes.* (e.g. .stack_sizes.foo)
as a normal stack sizes section. Though MC does not produce sections with
such names. Also, linkers do not combine .stack_sizes.* into .stack_sizes.

A mini discussion about this correctness issue is here: https://reviews.llvm.org/D67757#inline-609274
This patch changes implementation so that only now only '.stack_sizes' name is
accepted as a real stack sizes section.

George Rimar 4e0faa338b [llvm-readobj] - Implement LLVM-style dumping for .stack_sizes sections.
D65313 implemented GNU-style dumping (llvm-readelf).
This one implements LLVM-style dumping (llvm-readobj).

James Henderson be39e398e9 [llvm-readelf]Print filename for multiple inputs and fix formatting regression
This patch addresses two closely related bugs:
https://bugs.llvm.org/show_bug.cgi?id=42930 and
https://bugs.llvm.org/show_bug.cgi?id=42931.

GNU readelf prints the file name for every input unless there is only
one input and that input is not an archive. This patch adds the printing
for multiple inputs. A previous change did it for archives, but
introduced a regression with GNU compatibility for single-output
formatting, resulting in a spurious initial blank line. This is fixed in
this patch too.
