WIP: asm-generic: atomic-instrumented: add ordering variants
----
NOTE: this is an *incomplete* work in progress.
Many atomics have not yet been wrapped, and this *will not* compile!
----
Currently <asm-generic/atomic-instrumented.h> only instruments the fully
ordered variants of atomic functions, ignoring the {relaxed,acquire,release}
ordering variants.
This patch reworks the header to instrument all ordering variants of the atomic
functions, so that architectures implementing these are instrumented
appropriately.
To minimise repetition, a macro is used to generate each variant from a common
template. The {full,relaxed,acquire,release} order variants respectively are
then built using this template, where the architecture provides an
implementation.
To stick to an 80 column limit while keeping the templates legible, the return
type and function name of each template are split over two lines. For
consistency, this is done even when not strictly necessary.
