Add support for "-XX:+UseLargePages" option.

Excerpted from the original submission:

"FreeBSD on several architectures automatically utilizes superpages.  So,
for the JVM's JIT-compiled code cache and data heap, much of those regions
are already using superpages.  However, the -XX:+UseLargePages option still
serves a useful, if secondary, purpose on FreeBSD.  Essentially, it informs
the JVM's platform-independent layer what the supported page sizes are.  So,
when memory is mmap(2)ed and munmap(2)ed within the code cache and data
heap, the addresses and sizes will be superpage-aligned and a multiple of
the superpage size, respectively.  Currently, without this patch, the code
cache, for example, typically starts at an unaligned address, so the initial
portion of the code cache can never be a superpage.  Similarly, unaligned
munmap(2)s on the data heap force the kernel to demote superpages to 4KB
