This patch changes type variable lookup rules (lookupTypeOccRn) and
implicit quantification rules (filterInScope) so that variables bound
in the term namespace can be captured at the type level
{-# LANGUAGE RequiredTypeArguments #-}
f1 x = g1 @x -- `x` used in a type application
f2 x = g2 (undefined :: x) -- `x` used in a type annotation
f3 x = g3 (type x) -- `x` used in an embedded type
f4 x = ...
where g4 :: x -> x -- `x` used in a type signature
g4 = ...
This change alone does not allow us to accept examples shown above,
but at least it gets them past the renamer.

* Generalise the metric logic by adding an additional field which
allows you to specify how to query for the actual value. Previously
the method of querying the baseline value was abstracted (but always
set to the same thing).
* This requires rejigging how the stat collection works slightly but now
it's more uniform and hopefully simpler.
* Introduce some new "generic" helper functions for writing generic
stats tests.
- collect_size ( deviation, path )
Record the size of the file as a metric
- stat_from_file ( metric, deviation, path )
Read a value from the given path, and store that as a metric
- collect_generic_stat ( metric, deviation, get_stat)
Provide your own `get_stat` function, `lambda way: <Int>`, which
can be used to establish the current value of the metric.
- collect_generic_stats ( metric_info ):
Like collect_generic_stat but provide the whole dictionary of metric
definitions.
{ metric: {
deviation: <Int>
current: lambda way: <Int>
} }
* Introduce two new "size" metrics for keeping track of build products.
- `size_hello_obj` - The size of `hello.o` from compiling hello.hs
- `libdir` - The total size of the `libdir` folder.
* Track the number of modules in the AST tests
- CountDepsAst
- CountDepsParser
This lays the infrastructure for #24191 #22256 #17129

Now that we only have a single constructor for EpAnn, And it uses a
SrcSpan for its location, we can do away with SrcSpanAnn completely.
It only existed to wrap the original SrcSpan in a location, and
provide a place for the exact print annotation.
For darwin only:
