Some code conventions things mentioned, plus I do think we should fix the error handling from GetAPI.

This doesn't really check the return code from GetAPI - so if the user has, say, an older version of renderdoc.dll then it'll happily say "RenderDoc API initialized" and then not take a capture.
Related to this, I don't think we want to handle runtime errors like this with an assert.
| llvm::outs() << "RenderDoc API initialized.\n"; | ||
| } else { | ||
| DWORD error = GetLastError(); | ||
| llvm::outs() << "Failed to get renderdoc dll: " << error << "\n"; |

llvm::mapLastWindowsError() might be interesting to look at here. Looks like it should convert to strings as well.
Kinda hard to find the right balance for polish for a feature like this.

I don't know why the diffs on suggestions is so broken these days - anyway suggestion is to add braces around the else if.
Inconsistent bracing within if/else if/else chains (if one block requires braces, all must)

| if (Ret) { | ||

| // Initialize RenderDoc on Windows | ||
| #if defined(_WIN32) | ||
| if (HMODULE Mod = GetModuleHandleA("renderdoc.dll")) { |

This leaks the module. I don't know if we care about that though.
