re PR target/89474 (ice in df_reg_chain_verify_unmarked, at df-scan.c:3995)

PR target/89474
* config/i386/i386.c (remove_partial_avx_dependency): Call
df_analyze etc. before creation of the v4sf_const0 pseudo, rather than
after changing possibly many instructions to use that pseudo.  Fix up
insertion of v4sf_const0 setter at the start of bb.

* gcc.target/i386/pr89474.c: New test.
