Free large chunks in ggc v2
This implements the freeing back of large chunks in the ggc madvise path
Richard Guenther asked for. This way on systems with limited
address space malloc() and other allocators still have
a chance to get back at some of the memory ggc freed. The
fragmented pages are still just given back, but the address space
stays allocated.

pages, but the hit rate was quite low, so I switched to 1MB+
unaligned areas.

Add missing page rounding of a page_entry
This one place in ggc forgot to round page_entry->bytes to the
next page boundary, which lead to all the heuristics in freeing to
check for continuous memory failing. Round here too, like all other
allocators already do. The memory consumed should be the same
for MMAP because the kernel would round anyways. It may slightly
increase memory usage when malloc groups are used.
