Fixed 6712157: Tests should not use JDK64BIT file to set -d64 option

Problem:
Some HotSpot regression tests use a shell script which
checks that JDK6BIT file exists in user home directory to
run with -d64 option.
First, it causes different problems during testing,
for example, 32-bits and 64-bits testing can't be run
on the same machine in parallel.
Second, it is not needed for this test since run options (-d64)
are appended to the test options.

Solution:
Move the test options from the script to the jtreg command
specification in the .java file and remove the test script.
