Adds simple method inlining for select patterns only in the dart:_rti
library as an optimization. This helps avoid chains of costly
accesses method calls that in the end simply perform a single
operation and return the result.
For example and snipet from the compiled SDK before:
```
if (_rti._isString(object)) {...}
```
and after:
```
if(typeof object == "string") {...}
```
