Brief

Visual Studio 2019 16.8+ introduced new CodeView record formats, but not updated in cvinfo.h
Current llvm-pdbutil failed to parse those new records.

New record type 0x1609 LF_STRUCTURE2
Classic record type 0x1505 LF_STRUCTURE

Changes

uint16 property extended to uint32 property
uint64 count -> varint count
