Rollup merge of #63642 - eddyb:wrap-it-up, r=rkruppe,Mark-Simulacrum

Rename overflowing_{add,sub,mul} intrinsics to wrapping_{add,sub,mul}.

These confused @Gankra, and then, also me, especially since `overflowing_*` *methods* also exist, but they map to `*_with_overflow` intrinsics!

r? @oli-obk / @nikomatsakis cc @Mark-Simulacrum (on the rustbuild workaround)
