6795913: A few remaining wrong casts need to be fixed for building 
hotspot successfully on Mac OS.

Webrev: http://webrev.invokedynamic.info/xiaobin.lu/6795913/webrev/

Details:

This bug fix is to fix a few remaining wrong casts in order to build 
hotspot on Mac OS X. I accidentally left out a few places I supposed to 
fix as part of 6787106. The problem is again due to different definition 
of type intptr_t and int32_t on Mac OS.

Verified by:

Build on Mac OS X 10.5.5.

Thanks in advance!
