Use bit-level packing for InlineInfo in stackmaps as well.

Use bit-level packing for InlineInfo in stackmaps as well.

Use the same approach as we do for stackmaps to reduce the size.

It saves 4.0 MB from non-debuggable boot.oat (AOSP).
It does not affect debuggable boot.oat.

It saves 3.6 MB (of 96.6 MB) from /system/framework/arm/ (GOOG).
It saves 0.6 MB (of 26.7 MB) from /system/framework/oat/arm/ (GOOG).

Field loads from inline-info get around 5% slower.
(based on the time it takes to load all inline-infos from boot.oat)
