This is a reland of b9c521d0. Fixes crashes by calling kInstallBaselineCode from BaselineEntry if needed, i.e. when there is no feedback vector (required a bit of register rejiggling). This can happen with cross-realm calls. The OSR arming is stored as part of the BytecodeArray and therefore shared across realms.
