Fix string compression, add tests.

Fix String.compareTo() for interpreter; memcmp() does not
return the required result (only the right sign).
Fix x86-64 stub where the assembler silently accepted and
generated bad code for out-of-range JECXZ.
Add extensive tests for String.equals(), String.compareTo()

Test: Run ART test suite including interpreter tests on host and Nexus 9.
Test: Ditto with string compression enabled.

This helps to eliminate more dead induction. For example,
CaffeineLogic when compiled with latest Jack improves with
a 1.3 speedup (2900us -> 2200us) due to eliminating first
loop (second loop can be removed also, but for a later
