compiler.h: Add read_word_at_a_time() function.
[ Upstream commit 7f1e541fc8d57a143dd5df1d0a1276046e08c083 ]
Sometimes we know that it's safe to do potentially out-of-bounds access
because we know it won't cross a page boundary. Still, KASAN will
report this as a bug.
Add read_word_at_a_time() function which is supposed to be used in such
cases. In read_word_at_a_time() KASAN performs relaxed check - only the
first byte of access is validated.
