This will allow identifying exactly how many shadow bytes were used
during compilation, for when fast8 mode is introduced.

Also, it will provide a consistent matching point for instrumentation
tests so that the exact llvm type used (i8 or i16) for the shadow can
be replaced by a pattern substitution. This is handy for tests with
multiple prefixes.
