[PATCH] x86: Shrink writing 0/-1 to memory using and/or with -Oz.

This is the second part of my fix to PR target/103773 where -Oz shouldn't use push/pop on x86 to shrink writing small integer constants to memory. Instead clang uses "andl $0, mem" for writing zero, and "orl $-1, mem" when writing -1 to memory when using -Oz. This patch implements this via peepho

[AArch32]: correct dot-product RTL patterns.

Hi All, The previous fix for this problem was wrong due to a subtle difference between where NEON expects the RMW values and where intrinsics expects them. The insn pattern is modeled after the intrinsics and so needs an expand for the vectorizer optab to switch the RTL. However operand[3] is no
