82aea65bd3 UserspaceEmulator: Add fast-path for is<MmapRegion>() 
Don't use default RTTI for these since they are performance-sensitive.

89483a9408 UserspaceEmulator: Implement a proper VM allocator 
This patch brings Kernel::RangeAllocator to UserspaceEmulator in a
slightly simplified form.

It supports the basic three allocation types needed by virt$mmap():
allocate_anywhere, allocate_specific, and allocate_randomized.

Porting virt$mmap() and virt$munmap() to use the allocator makes
UE work correctly once again. :^)
