Support computed properties for ES2015 Function.name

Adds a new runtime function, %DefineDataPropertyInLiteral, which
takes a fifth argument specifying whether the property and value
are syntactically such that the value is a function (or class)
literal that should have its name set at runtime.

The new runtime call also allows us to eliminate the now-redundant
%DefineClassMethod runtime function.

This should get much less ugly once we can desugar the "dynamic"
part of object literals in the parser (but that work is currently
blocked on having a performant way of desugaring literals).
