Description
A DESCRIPTION OF THE REQUEST :
Additionally consider default inlining of very small methods with few call sites.

JUSTIFICATION :
- Reduces memory usage
- Increases performance
- Reduces register pressur in many cases
Comments
Always inlining methods which have only 1 call site might not always be faster (code size, register allocation). It might be true for very small methods but for these we have MaxTrivialSize.
