lld-link: Add a flag /lldignoreenv that makes lld-link ignore env vars. This is useful for enforcing that builds are independent of the environment; it can be used when all system library paths are added via /libpath: already. It's similar ot cl.exe's /X flag. Since it should also affect %LINK% (the other caller of `Process::GetEnv` in lld/COFF), the early-option-parsing needs to move around a bit. The options are: - Add a manual loop over the argv ArrayRef and look for "/lldignoreenv". This repeats the name of the flag in both Options.td and in DriverUtils.cpp. - Add yet another table.ParseArgs() call just for /lldignoreenv before adding %LINK%. - Use the existing early ParseArgs() that's there for --rsp-quoting and use it for /lldignoreenv for %LINK% as well. This means --rsp-quoting and /lldignoreenv can't be passed via %LINK%. I went with the third approach.
