Issue :
=======
Setting query_cache_size to larger values might fail depending on the
memory pressure being put on the system. This can be seen on pushbuild
as the test case query_cache_size_basic tries to allocate a +3GB query
cache, which succeeds in some machines and fails in others.

Both query_cache_size_basic_32.test and query_cache_size_basic_64.test
are disabled.

Fix :
=====
Since query_cache_size value can change depending on the memory pressure
being put on the machine, remove/comment the test cases with large
query_cache_size value and enable the tests.

Modified myisam_sort_buffer_size_basic.inc to make 32-bit version of the
test to run on windows 64 bit machine.
