[Gc] Some minor fixes for test.c

Hi!

This patch does some code polishing in test.c:
- adjusts actual parameter type according to format specifier for GC_printf() calls;
- removes "unused result of expression" for GC_PRE/POST_INCR/DECR() invocations (by casting to "void" type);
- casts some values to GC_word (or size_t) to prevent overflow or compiler warning (useful for Win64);
- comments out "FAIL" (at least, temporarily) on "Unexpected heap growth" (since its trigging condition seems to be wrong - e.g. in Win32 with THREAD_LOCAL_ALLOC+PARALLEL_MARK the condition is violated frequently).

Bye.
