Subject: [PATCH] emit DW_AT_name for DW_TAG_GNU_formal_parameter
If two arrays do not have the exact same element type including qualification,
this could be e.g. f(int (&&)[]) vs. f(int const (&)[]), which can still be
distinguished by the lvalue-rvalue tiebreaker.
By tightening this branch (in accordance with the letter of the Standard) we
fall through to
nd tested on x86_64-pc-linux-gnu.

This patch series improves conformance to the C++ standard for C-style casts
(explicit cast notation, [expr.cast]) in two scenarios.
First, as discussed in CWG 909 [1], a C-style cast may invoke a user-defined
conversion (as a static_cast) followed by a const_cast; currently this is
erroneously
PR c++/77465 - [DR909] rejected C-style cast involving casting away constness
from result of conversion operator
