Inline memove for small constant sizes and refactor memcpy and memset.

 # The following variables will likely need to be modified, depending on where
 # and how you built LLVM & Clang. They can be overridden in a command-line
 # invocation of make, like:
 #
 #   make LLVM_SRC_PATH=<path> LIBCXX_INSTALL_PATH=<path> CLANG_PATH=<path> \
 #        PNACL_BIN_PATH=<path> ...
 #
 
 # LLVM_SRC_PATH is the path to the root of the checked out source code. This
 # directory should contain the configure script, the include/ and lib/

Thanks =)

Would it make sense to put this by the "ifdef CHECK_X86_ASM" block instead, so
that at least other unittests could run w/ or without DEBUG?

Done.
