Tess Strickland d017b8eee8 [vm] Compress CodeSourceMaps by folding opcodes and arguments. ...

Also delta encode the position/line argument for ChangePosition.

Code size changes on Flutter gallery in release mode from compression:

* ARM7: total -1.39%, readonly -6.47%
* ARM8: total -1.28%, readonly -4.81%

Additional code size changes on Flutter gallery in release mode from
delta encoding position/line:

* ARM7: total -0.48%, readonly -2.37%
* ARM8: total -0.54%, readonly -2.09%

TEST=Existing test on trybots, including stack trace tests and
DWARF decoding tests.
