[Bug debug/19192] [4.3/4.4/4.5 Regression] Current development gcc generates inaccurate line info for example code

[matz at gcc dot gnu dot org]

It should mostly not matter anymore as expand_expr_real_[12] and friends use
an explicit location parameter, stored away before expanding operands.
But to be safe, yes, expand_expr_real() should instead also restore
the old location.  You don't need to check for NULL gimple_block(),
set_curr_insn_block does that.
