[PATCH 0/3] MR9284: Enfore SymLoadModuleEx(..., SLMFLAG_NO_SYMBOLS) for all debug formats.
This serie ensures that a module loaded in dbghelp with SLMFLAG_NO_SYMBOLS always doesn't load symbol (except the ones from the EXPORT table of the PE image).
To be implemented correctly, it requires a refactoring of the way dbghelps looks up for a debug format.

- respect SymLoadModuleEx(..., SLMFLAG_NO_SYMBOLS) for all formats. - reorder search logic: + matched .pdb + matched .dbg + dwarf + stabs + other debug formats in PE DEBUG directory (codeview...) + other debug formats from PE header (coff...) + unmatched .pdb (if none of previous worked). - only one of these format is loaded (while previously we could merge some of them), - use module's export table in last resort (either SLMFLAG_NO_SYMBOLS is present, or no debug info found) - for handling .pdb/.dbg, separate 1) getting .pdb/.dbg information from image, 2) searching a matching .pdb/.dbg file, 3) loading debug information from that very file.
Note: - we no longer fill CVData field in extended module info.
