  [clang] Ensure -mno-outline adds attributes

Before this change, `-mno-outline` and `-moutline` only controlled the
pass pipelines for the invoked compiler/linker.

The drawback of this implementation is that, when using LTO, only the
flag provided to the linker invocation is honoured (and any files which
individually use `-mno-outline` will have that flag ignored).

This change serialises the `-mno-outline` flag into each function's
IR/Bitcode, so that we can correctly disable outlining from functions in
files which disabled outlining, without affecting outlining choices for
functions from other files. This matches how other optimisation flags
are handled so the IR/Bitcode can be correctly merged during LTO.
