testsuite: Add mechanism to collect generic metrics

* 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

EPA: Remove SrcSpanAnn

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:

testsuite: don't initialize testdir to '.'

The test directory is removed during cleanup, if there's an interrupt
that could remove the entire repository.

Fixes #24219

Now that we have HasLoc we can get rid of all the custom variants of
mkScope

distrib: Rediscover otool and install_name_tool on Darwin

In the bindist configure script we must rediscover the `otool` and
`install_name_tool`s since they may be different from the build
environment.

Fixes #24211.

llvmGen: Align objects in the data section

Objects in the data section may be referenced via tagged pointers.
Thus, align those objects to a 4- or 8-byte boundary for 32- or 64-bit
platforms, respectively.  Note, this may need to be reconsidered if
objects with a greater natural alignment requirement are emitted as e.g.
128-bit atomics.

Fixes #24163.

metrics: Widen libdir and size_hello_obj acceptance window

af8816740d9b8759be1a22af8adcb5f13edeb61d shows that the libdir size can
fluctuate quite significantly even when the change is quite small.
Therefore we widen the acceptance window to 10%.

nor wrapLocAM, wrapLocSndMA.

T2T in Patterns (#23739)

This patch implements the T2T (term-to-type) transformation in patterns.
Patterns that are checked against a visible forall can now be written
without the `type` keyword:

	  \(type t) (x :: t) -> ...   -- old
	  \t (x :: t) -> ...          -- new

The `t` binder is parsed and renamed as a term pattern (Pat), but
then undergoes a conversion to a type pattern (HsTyPat).
See the new function pat_to_type_pat in compiler/GHC/Tc/Gen/Pat.hs
