<pre>cmake runs mt.exe on the linker output after the linker finishes to embed
Windows manifest files in the binary. mt.exe doesn't expect to find a
COFF-style symbol table in a PE image, so the PointerToSymbolTable field ends
up pointing past the end of the binary.
At high level, I'm trying to self-host clang with lld and asan on Windows. I
need to preserve the PE symbol table so that the long section names used by
DWARF (.debug_info) work.
For now, I can convince cmake that it doesn't need to add a manifest to our
binaries, and that will probably work. However, it would be nice if LLD or LLVM
provided some solution, like a replacement for mt.exe if it's trivial, that
avoided the problem altogether.</pre>
