[dart/vm] Improved inlining methods and heuristics

Rationale:
Previous method cached graph information (instruction and call site
counts) on a per-function level, not accounting for potential
specializations. The improved method runs an extra constant folding
pass, and only caches per-function information for non-specialized
cases. As a result, we inling much better, see for example, the
added test as illustration.

Since we no longer cache for constants, compile-time may be increased
a bit due to the extra scan. In the long run we should consider
for common constant "situations" as the call site.
