Revert "[InstCombine] Recognize `((x * y) s/ x) !=/== y` as an signed multiplication overflow check (PR48769)"
This reverts commit 13ec913bdf500e2354cc55bf29e2f5d99e0c709e.
This commit introduces new uses of the overflow checking intrinsics that
depend on implementations in compiler-rt, which Windows users generally
do not link against. I filed an issue (somewhere) to make clang
auto-link the builtins library to resolve this situation, but until that
happens, it isn't reasonable for the optimizer to introduce new link
time dependencies.
