Do you mean will it make an asan runtime library **built** with the intel toolchain work, or will it make `-fsanitize=address` work with the intel compiler? I think the answer to both should be yes, but I'm not 100% certain. This change was motivated by our (I'm a developer for ICX) internal testing showing failures for asan unitests.

MSVC's `link.exe` by default, though some compiler options (for example LTO and offloading) implicitly cause `lld-link` to be used instead, I don't know if `-fsanitize=address` is among them.
