creating workflow for mirror::String compression
All-ASCII String characters are stored in 8-bit blocks
instead of 16-bit. The compression has not taken place, but all
workflow are in the code already (changing kUseStringCompression in
string.h file to TRUE will enable the feature)
Notes: Feature works on interpreter only without optimizing
Test art: m ART_TEST_INTERPRETER=true ART_TEST_OPTIMIZING=false
test-art-host
Also tested with String tests from libcore/:
1. libcore.java.lang.StringTest
2. libcore.java.lang.StringBufferTest
3. libcore.java.lang.StringBuilderTest
4. libcore.java.lang.OldStringTest
5. libcore.java.lang.OldStringBufferTest
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

Intercept JNI invocation of String.<init> methods.
libmono uses JNI AllocObject and CallNonvirtualVoidMethod to create and
initialize a string instead of using the recommended NewObject. This
change adds an intercept to change the String.<init> call to a
StringFactory call instead. Then, it uses the object id of the original
string object referrer and maps it to the result of the StringFactory.

Adding old unit tests to test suite.
These tests are copied straight over. They'll still run, but they're
using the old system.
