VLF to use 1MB pages

VLF is used for caching modules and other objects to speed up access in a system.

1MB pages would be a good thing for VLF to use, if specifically told to make use of them.

    Backing all VLF-managed caches with 1M pages might not overall be an effective use of 1M pages. However, we may consider backing the VLF-managed cache that LLA uses, to cover the case of executable program modules.

    We will consider backing with 1M pages the storage used by VLF to cache module data requested by LLA. Other VLF data spaces will not be changed.
