Modifying Length() and access to field count to neglect
the first bit of count for mirror::String compression purpose
(All-ASCII String will be stored in 8-bit characters instead of 16-bit)
Memory improvement is 33% (from 6.03% to 4.03%, total String memory
from all apps per total memory of all apps) measured on Angler
with Hprof tools
Test: vogar --benchmark libcore/benchmarks/src/benchmark/regression
