Force the Docs structure to prevent leaks in GHCi with -haddock without -fwrite-interface

Involves adding many new NFData instances.

Without forcing Docs, references to the TcGblEnv for each module are retained
by the Docs structure. Usually these are forced when the ModIface is serialised
but not when we aren't writing the interface.

compiler: Add -f[no-]split-sections flags

Here we add a `-fsplit-sections` flag which may some day replace
`-split-sections`. This has the advantage of automatically providing a
`-fno-split-sections` flag, which is useful for our packaging because we
enable `-split-sections` by default but want to disable it in certain
configurations.

hadrian: Add no_split_sections tranformer

This transformer reverts the effect of `split_sections`, which we intend
to use for platforms which don't support split sections.

In order to achieve this we have to modify the implemntation of the
split_sections transformer to store whether we are enabling
split_sections directly in the `Flavour` definition. This is because
otherwise there's no convenient way to turn off split_sections due to
having to pass additional linker scripts when merging objects.

as "werror".

packaging: Build perf builds with -split-sections

In 8f71d958 the make build system was made to use split-sections on
linux systems but it appears this logic never made it to hadrian.
There is the split_sections flavour transformer but this doesn't appear
to be used for perf builds on linux.

This is disbled on deb9 and windows due to #21670

Closes #21135
