This patch would like to allow IMM for the operand 0 of ussub pattern.
Aka .SAT_SUB(1023, y) as the below example.

Hi,
This patch adds const0 move checking for CLEAR_BY_PIECES. The original
vec_duplicate handles duplicates of non-constant inputs. But 0 is a
constant. So even a platform doesn't support vec_duplicate, it could
still do clear by pieces if it supports const0 move by that mode.
Compared to the

In ext_dce_process_uses we can be presented with something like this as
