PR target/39139
* function.h (struct function): Add has_local_explicit_reg_vars
bit.
* gimplify.c (gimplify_bind_expr): Set it if local DECL_HARD_REGISTER
VAR_DECLs were seen.
* tree-ssa-live.c (remove_unused_locals): Recompute
cfun->has_local_explicit_reg_vars.
* tree-ssa-sink.c (statement_sink_location): Don't sink BLKmode
copies or clearings if cfun->has_local_explicit_reg_vars.
* gcc.target/i386/pr39139.c: New test.
