Description

Building runtime with clang-13 or newer, both lldb and gdb will fail to parse many of the common c++ objects.

Reproduction Steps

build.sh -rc checked -lc release -s clr+libs --clang13
gdb --args corerun helloworld.dll
b compCompile
run
p *this

Similar reproduction with lldb

Expected behavior

(gdb) p *this
$1 = {static MAX_SPILL_TEMP_SIZE = 24, static CHECK_SPILL_ALL = 4294967295, static CHECK_SPILL_NONE = 4294967294,
static MAX_TREE_SIZE = 200, static jitTotalMethodCompiled = 0, static jitNestingLevel = 0, static MAX_CSE_CNT = 64,
static MIN_CSE_COST = 2, static s_optCSEhashSizeInitial = 128, static s_optCSEhashGrowthFactor = 2,
static s_optCSEhashBucketSize = 4, static optEarlyPropRecurBound = 5,
etc

Actual behavior

(gdb) p *this
$1 = <incomplete type>

Regression?

Works with llvm-12

Known Workarounds

Build with llvm-12

Configuration

X64 or Arm64
Ubuntu Linux 22.04

Other information

Feels like this is bad DWARF information.
Possibly related to #90209 ?
