re PR target/78791 (ACATS cxf2001 failure)
PR target/78791
* config/i386/i386.h (enum ix86_stack_slot): Add SLOT_STV_TEMP.
* config/i386/i386.c (dimode_scalar_chain::make_vector_copies,
dimode_scalar_chain::convert_reg): Use SLOT_STV_TEMP instead of
SLOT_TEMP.
* gcc.c-torture/execute/pr78791.c: New test.
* gcc.target/i386/pr78791.c: New test.
