[classlib] initial port to x86_64 platform
------------------------------------------

                 Key: HARMONY-1005
                 URL: http://issues.apache.org/jira/browse/HARMONY-1005
             Project: Harmony
          Issue Type: Improvement
          Components: Classlib
         Environment: Linux, X86_64
            Reporter: Marina V. Goldburt
         Attachments: classlib_em64t_patch.txt, drlvm_port_patch.txt

the classlib_em64t_patch.txt patch allows the classlib to be compiled and run under Linux/x86_64
platform.

the drlvm_port_patch.txt was done only for testing purposes, it allows the DRLVM to be compiled
and run Linux/x86_64 platform in the interpreter mode.

to test the patch:

1. checkout classlib under Linux/x86_64 environment
2. apply patch classlib_em64t_patch.txt
3. create depends/libs/linux.x86_64 directory 
4. build and copy there x86_64 version of icu* libraries
5. download dependencies
6. build classlib: ant -Dos.arch=x86_64
    Note: setting os.arch manually is necessary as Ant doesn't set os.arch correctly
7. checkout DRLVM
8. apply patch  drlvm_port_patch.txt
9. change remote.ECLIPSE.location in the build/make/lnx.properties to point it to the x86_64
eclipse build
    or set ECLIPSE_HOME to the appropriate location
10. build DRLVM
11. Run eclipse.sh script under deploy/jre/bin directory to test the build.

As jitrino doesn't support x86_64 platform, use java -Xint  <some class> to test it.
