Which @angular/* package(s) are the source of the bug?

compiler

Is this a regression?

No

Description

Consider text interpolate in a template: {{ {name: 'Angular'} | json }}. Since we are declaring an object in a template, the generated code would be along the lines of: textInterpolate1(" ", pipeBind1(1, 1, pureFunction0(3, _c0)), " "); (where _c0 = ()=>({ name: "Angular" });.

Notice that we generate an arrow function wrapper around _c0 and the pureFunction call - even if {name: 'Angular'} is an object literal that will never change. We could optimize for such case and skip the pureFunction0 instruction call (alongside with the arrow function for _c0).
