[PATCH] tree-optimization/109672 - properly check emulated plus during vect

The following refactors the check for emulated vector support for the cases of plus, minus and negate. In the PR we end up with a SImode plus, supported by the target but emulated and in this context fail to verify we are dealing with exactly word_mode. Bootstrapped and tested on

[PATCH] [i386] Fix testcases for emulated scatter

The following adjusts testcases where the pr88531 fail with -m32 because we do not consider MMX size vectorization there and the pr89618 runs into load/store cost differences with -m32. Tested on x86_64-unknown-linux-gnu, pushed. * gcc.target/i386/pr88531-2a.c: Skip scanning for ia32.

Hi! The following patch regenerates the ABI files (I've only changed the Linux files which were updated recently (last month)). Tested on x86_64-linux, ok for trunk and later 13.2? 2023-05-02 Jakub Jelinek * config/abi/post/aarch64-linux-gnu/baseline_symbols.txt: Update. *
