  [clang] Adjust -mlarge-data-threshold handling (#77958)

Make it apply to x86-64 medium and large code models since that's what
the backend does.

Limit logic to exclude x86-32.

Default to 0, let the driver set it to 65536 for the medium code model
if one is not passed. Set it to 0 for the large code model by default to
match gcc and since some users make assumptions about the large code
model that any small data will break.
