From: xuli
vsetvl pass has been refactored in gcc14, and the optimization
is more reasonable than releases/gcc-13. This problem does not
exist in gcc14.
Phase 6 of gcc13 is an optimization patch. Due to lack of consideration,
there will be some hidden bugs, so we decided to remove phase 6.

Author: Jiufu Guo
Date: Wed Sep
According to PR: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110751
As Richard and Richi suggested, we recognize uninitialized SSA_NAME and convert
it
into SCRATCH rtx if the target predicate allows SCRATCH.
It can help to reduce redundant data move instructions of targets like RISC-V.
