[clang][test][NFC] Also test for serialization in AST dump tests, part 1/n. The outputs between the direct ast-dump test and the ast-dump test after deserialization should match modulo a few differences. For hand-written tests, strip the "<undeserialized declarations>"s and the "imported"s with sed. For tests generated with "make-ast-dump-check.sh", regenerate the output. Part 1/n.

[clang] Rework how and when APValues are dumped Currently APValues are dumped as a single string. This becomes quickly completely unreadable since APValue is a tree-like structure. Even a simple example is not pretty: struct S { int arr[4]; float f; }; constexpr S s = { .arr = {1,2}, .f = 3.1415f }; // Struct fields: Array: Int: 1, Int: 2, 2 x Int: 0, Float: 3.141500e+00 With this patch this becomes: -Struct |-field: Array size=4 | |-elements: Int 1, Int 2 | `-filler: 2 x Int 0 `-field: Float 3.141500e+00 Additionally APValues are currently only dumped as part of visiting a ConstantExpr. This patch also dump the value of the initializer of constexpr variable declarations: constexpr int foo(int a, int b) { return a + b - 42; } constexpr int a = 1, b = 2; constexpr int c = foo(a, b) > 0 ? foo(a, b) : foo(b, a); // VarDecl 0x62100008aec8 <col:3, col:57> col:17 c 'const int' constexpr cinit // |-value: Int -39 // `-ConditionalOperator 0x62100008b4d0 <col:21, col:57> 'int' // <snip> Do the above by moving the dump functions to TextNodeDumper which already has the machinery to display trees. The cases APValue::LValue, APValue::MemberPointer and APValue::AddrLabelDiff are left as they were before (unimplemented). We try to display multiple elements on the same line if they are considered to be "simple". This is to avoid wasting large amounts of vertical space in an example like: constexpr int arr[8] = {0,1,2,3,4,5,6,7}; // VarDecl 0x62100008bb78 <col:3, col:42> col:17 arr 'int const[8]' constexpr cinit // |-value: Array size=8 // | |-elements: Int 0, Int 1, Int 2, Int 3 // | `-elements: Int 4, Int 5, Int 6, Int 7 Differential Revision: https://reviews.llvm.org/D83183 Reviewed By: aaron.ballman

PR46209: properly determine whether a copy assignment operator is trivial. We previously took a shortcut by assuming that if a subobject had a trivial copy assignment operator (with a few side-conditions), we would always invoke it, and could avoid going through overload resolution. That turns out to not be correct in the presenve of ref-qualifiers (and also won't be the case for copy-assignments with requires-clauses either). Use the same logic for lazy declaration of copy-assignments that we use for all other special member functions. Previously committed as c57f8a3a20540fcf9fbf98c0a73f381ec32fce2a. This now also includes an extension of LLDB's workaround for handling special members without the help of Sema to cover copy assignments.

We previously took a shortcut by assuming that if a subobject had a trivial copy assignment operator (with a few side-conditions), we would always invoke it, and could avoid going through overload resolution. That turns out to not be correct in the presenve of ref-qualifiers (and also won't be the case for copy-assignments with requires-clauses either).
