  [Driver][HIP/SPIRV] Fix crash when llvm-link is executed.

There is a design limitation that is forwarding flags to llvm-link
when it shouldn't happen. This commit fixes this issue by sanitizing
the arguments forwarded to llvm-link.

This may happen when clang-linker-wrapper eventually calls clang.
Crash reproducer is here: https://gcc.godbolt.org/z/rxvWcvan3.

The fix is based on MrSidims's old PR (#183492).
