re PR rtl-optimization/78575 (ICE: in trunc_int_for_mode, at explow.c:55 with -O2 -g)

PR rtl-optimization/78575
* config/i386/i386.c (timode_scalar_chain::fix_debug_reg_uses): Use
DF infrastructure to wrap all V1TImode reg uses into TImode subreg
if not already wrapped in a subreg.  Make sure df_insn_rescan does not
affect further iterations.

* gcc.dg/pr78575.c: New test.
