Inline small closure functions (e.g: `locationRangeGetter`)

[SupunS]

Issue To Be Solved

While adding some runtime changes, I noticed that small closure functions can lead to performance degradations. e.g: Use of locationRangeGetter function in a hot-path decreased the performance by ~20% (compared to inlining).

Suggested Solution

We should inline such commonly used small closure functions. Currently known ones are:

• [ ] locationRangeGetter
