[PATCH] [x86] Replace REGNO with reg_or_subregno in pre_reload splitter.

[liuhongt via Gcc-patches]

The patch is similar to [1], but use reg_or_subregno instead of REGNO.

[1] https://gcc.gnu.org/pipermail/gcc-patches/2022-June/596804.html

Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,}.
Ok for trunk?
