Mark getpagesize() const.
If folks want to use this instead of PAGE_SIZE, let's let the compiler
know that it doesn't need to be called more than once. Using "const"
rather than "pure" lets us cover more cases, and although this function
may need to check global state, it's _immutable_ global state, so it's
effectively "const".
Test: llvm-objdump -d
