[PR71478] Fix ICE in tree-ssa-reassoc.c

[kugan <kugan dot vivekanandarajah at linaro dot org>]

Hi,

In PR71478, for vector negation of ssa produced by call stmt, we add 
vector (-1) and ssa to the ops list. However, in the place where we 
remove the (-1) from ops list, we failed to do this for vector integer. 
As a result, rewrite_expr_tree wrongly assumes that it is working with 
gimple_assign.

Attached patch fixes the place where we remove the vector (-1).

Regression tested on x86-64-linux-gnu with no new regressions. 
Regression testing on aarc64-linux-gnu is ongoing. Is this OK for trunk?

Thanks,
Kugan
