[PATCH v3 0/2] Make GDB respect the DW_CC_nocall attribute

[Lancelot SIX <lancelot.six@amd.com>]

Hi,

This is a V3 following
https://sourceware.org/pipermail/gdb-patches/2022-January/185563.html.

Noticeable changes since V2:

- Instead of using get_function_name (COREADDR, ...) in order to format
  messages displayed to the user in get_return_value, this series now
  ensures that the function's symbol is passed to get_return_value.
  With the symbol available, getting the function name is a matter of
  calling 'symbol::print_name'.  This overall simplifies the
  implementation.

  To simplify the review process, changes required to have the symbol in
  get_return_value are done in a preparatory patch.

- Fix coding style issues reported by Bruno.

- Remove newline at the end of the testcase.

Thanks to Bruno and Simon for the comments.

Tested on x86_64-linux with no regression observed.

All feedback welcome.

Best,
Lancelot.
