Add more dwarf debug line info for Optimized methods.
Optimizing compiler generates minimum debug line info that
is built using the dex_pc information about suspend points.
This is not enough for performance and debugging needs.
This CL generates additional debug line information for
instructions which have known dex_pc and it ensures that
whole call sites are mapped (as opposed to suspend points
which map only one instruction past the function call).
