mm: replace __ASSEMBLY__ with __ASSEMBLER__ in memory management header files

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a macro that
only gets defined by the Makefiles in the kernel.  This can be very
confusing when switching between userspace and kernelspace coding, or when
dealing with uapi headers that rather should use __ASSEMBLER__ instead. 
So let's standardize now on the __ASSEMBLER__ macro that is provided by
the compilers.

This is a completely mechanical patch (done with a simple "sed -i"
statement).
