re PR rtl-optimization/78547 (ICE: in loc_cmp, at var-tracking.c:3417 with -Os -g -mstringop-strategy=libcall -freorder-blocks-algorithm=simple)
PR rtl-optimization/78547
* emit-rtl.c (unshare_all_rtl): Make sure DECL_RTL and
DECL_INCOMING_RTL is not shared.
* config/i386/i386.c (convert_scalars_to_vectors): If any
insns have been converted, adjust all parameter's DEC_RTL and
DECL_INCOMING_RTL back from V1TImode to TImode if the parameters have
TImode.
* gcc.dg/pr78547.c: New test.
