Mostly size_t <-> unsigned int warnings, but I also had a mistake in PROCESS_BASIC_INFORMATION, the pids are 32-on-32 and 64-on-64. The Windows build is still x86 until https://codereview.chromium.org/981333002/. I don't think I'll bother maintaining the x86 build for now, though we will probably need it for x86 OSs in the future. It should be straightforward to revive it once we need it, and have bots to support it. R=mark@chromium.org BUG=crashpad:1 Review URL: https://codereview.chromium.org/983103004
