Reduce quicken info size

Move the quicken info from using a map of <dex pc, index> to an array
of indices. Removed leb encoding since it is harmful for 16 bit
indices. The map is indexed by the dequickenable instruction index
from the start of the code item.

Numbers for a certain large app compiled with quicken filter:
dex2oat native alloc: 85345936B -> 81527072B
oat file size: 9068968B -> 8659368B
vdex file size: 90479120B -> 86321184B
