The log priorities and ids are in an NDK header, available to everyone.
Move CHECK into its own header for now. This would be better if it was
more like the <android-base/logging.h> CHECK family, but I don't have an
easy way to do that without lots of copy & paste, so punting for now.

Bionic needs this functionality to allocate a TLS segment with greater
than 16-byte alignment. For simplicity, this allocator only supports up
to one page of alignment.
The memory layout changes slightly when allocating an object of exactly
PAGE_SIZE alignment. Instead of allocating the page_info header at the
start of the page containing the pointer, it is allocated at the start
of the preceding page.

Rename LinkerMemoryAllocator -> BionicAllocator
Rename LinkerSmallObjectAllocator -> BionicSmallObjectAllocator
libc and the linker need to share an instance of the allocator for
allocating and freeing dynamic ELF TLS memory (DTVs and segments). The
linker also continues to use this allocator.
