re PR rtl-optimization/34998 (gcc.c-torture/execute/20040709-1.c fails for -EL -mips16 -O3)

PR rtl-optimization/34998
* global.c (build_insn_chain): Treat non-subreg_lowpart
SUBREGs of pseudos as clobbering all the words covered by the
SUBREG, not just all the bytes.
* ra-conflict.c (clear_reg_in_live): Likewise.  Take the
original df_ref rather than an extract parameter.
(global_conflicts): Update call accordingly.
