[PATCH v2 0/8] Fix inferior call for C++ pass-by-reference arguments

[Tankut Baris Aktemur <tankut dot baris dot aktemur at intel dot com>]

Hi All,

This is a set of patches to fix GDB's conformance to C++ ABI when
invoking functions that have call-by-value arguments of aggregate
types that should be implicitly passed by reference.

The v1 of the series is available at
https://sourceware.org/ml/gdb-patches/2019-04/msg00461.html

Changes since v1:
* Patches 1-3 have been revised according to the reviews
  (thanks to Andrew Burgess).
* The patches have been rebased to the current master.

Regards,
-Baris

  gdb: recognize new DWARF attributes: defaulted, deleted, calling conv.
  infcall, c++: allow more info to be computed for pass-by-reference
    values
  infcall, c++: collect more pass-by-reference information
  infcall: refactor 'call_function_by_hand_dummy'
  infcall: move assertions in 'call_function_by_hand_dummy' to an
    earlier spot
  infcall: remove unused parameter in 'value_arg_coerce'
  infcall: handle pass-by-reference arguments appropriately
  testsuite, cp: increase the coverage of testing pass-by-ref arguments
