  [JSC] Adjust inlining options

Reviewed by Justin Michaud.

This patch extends JSC to have different inlining options for DFG and FTL.
This is great since DFG and FTL have different purpose and we would like
to make DFG smaller-compilation and faster and keeping FTL heavy and highly optimized.
And then, we adjust these numbers based on benchmarks.

1. DFG inlining heuristics becomes 80.
2. FTL call inlining heuristics becomes 125.
