PATCH: max_heap_for_compressed_oops() declared with size_t, but defined with uintx

[Dan Horák]

Hello,

I've created a patch [1] to fix usage of uintx where size_t type is
expected in hotspot/src/share/vm/runtime/arguments.cpp

The Arguments::max_heap_for_compressed_oops() method is declared in
arguments.hpp as
	size_t max_heap_for_compressed_oops()
but later defined in arguments.cpp as
	uintx max_heap_for_compressed_oops()

For most platforms the uintx and size_t types are effectively the
same, so the interchange is uncaught, but on s390 (32-bit) the size_t is
"unsigned long" which makes it incompatible with "unsigned int".

This a follow-up of my earlier s390 related patch [2]
