RFR(S): 8157956 - OverflowCodeCacheTest.java fails with Out of space in CodeCache for method handle intrinsic

[Dmitrij Pochepko]

Hi,

please review small fix for 8157956 - OverflowCodeCacheTest.java fails 
with Out of space in CodeCache for method handle intrinsic

Test failed with "VirtualMachineError: Out of space for method handle 
intrinsic" because of code cache exhaustion. This happened on final 
assert. This fix moves assert after freeing codecache logic to get rid 
of error.

I've tested it on linux-i586
