Natvis is a debug language supported by Visual Studio for specifying custom visualizers. The /NATVIS option is an undocumented link.exe flag which will take a .natvis file and "inject" it into the PDB. This way, you can ship the debug visualizers for a program along with the PDB, which is very useful for postmortem debugging. This is implemented by adding a new "named stream" to the PDB with a special name of /src/files/<natvis file name> and simply copying the contents of the xml into this file. Additionally, we need to emit a single stream named /src/headerblock which contains a hash table of embedded files to records describing them. This patch adds this functionality, including the /NATVIS option to lld-link.
