The `asBox` function is intended to store exactly the closure which the
user passes to it. Placing a cost centre on asBox introduces a thunk,
which violates this expectation and can change the result of using asBox
when profiling is enabled.
See #25212 for more details and ample opportunity to discuss if this is
a bug or not.

Fix 1: If a cost centre contained CAF then the normalisation was
corrupted, now only check if CAF is at the start of a line.
Fix 2: "no location info" contain a space, which messed up the next
normalisation logic which assumed that columns didn't have spaced in.

These normalisation steps were collapsing lines together, which made
subsequent normalisation steps fail.
```
foo x y z
CAF x y z
qux x y z
```
was getting normalised to
```
foo x y z qux x y z
```
which means that subsequent line based filters would not work correctly.

This enables late cost centres when building profiled libraries and
subsequently greatly improves the resolution of cost centre stacks when
profiling.
This patch also introduces the `grep_prof` test modifier which is used
to apply a further filter to the .prof file before they are compared.
