[DRLVM][JIT] wrong array element size calculated for allocArray helper inlining
-------------------------------------------------------------------------------

                 Key: HARMONY-3911
                 URL: https://issues.apache.org/jira/browse/HARMONY-3911
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: windows and linux
            Reporter: Yu-Nan He


During the investigation of HARMONY-3899, I found the failure is caused by a wrong array element
size passed to GC. 

When running
java -Xmx1500M -Xms1500M -Xem:server -XX:vm.dlls=gc_gen.dll -XX:gc.use_large_page=true -cp
. Harness -n 10 hsqldb 

in some iteration, allocArray helper is invoked to create an array of [Z type with length
of 13. But the element size is set to be 4 (for one Byte). Then the calculated array object
size is wrong. 

It would be great if some JIT guru can help to fix it. Thanks.
