re PR target/66470 (TLS ICE due to ix86_split_long_move)
PR target/66470
* config/i386/i386.c (ix86_split_long_move): For collisions
involving direct tls segment refs, move the UNSPEC_TP possibly
wrapped in ZERO_EXTEND out of the address for lea, to each of
the memory loads.
* gcc.dg/tls/pr66470.c: New test.
* gcc.target/i386/pr66470.c: New test.
