Substantial improvements to coercion optimisation
The main purpose of this patch is to add a bunch of new rules
to the coercion optimiser. They are documented in the (revised)
Appendix of the System FC paper.
Some code has moved about:
- OptCoercion is now a separate module, mainly because it
now uses tcMatchTy, which is defined in Unify, so OptCoercion
must live higehr up in the hierarchy
- Functions that manipulate Kinds has moved from
Type.lhs to Coercion.lhs. Reason: the function typeKind
now needs to call coercionKind. And in any case, a Kind is
a flavour of Type, so it builds on top of Type; indeed Coercions
and Kinds are both flavours of Type.
This change required fiddling with a number of imports, hence
the one-line changes to otherwise-unrelated modules
- The representation of CoTyCons in TyCon has changed. Instead of
an extensional representation (a kind checker) there is now an
intensional representation (namely TyCon.CoTyConDesc). This was
needed for one of the new coercion optimisations.

Bottom extraction: float out bottoming expressions to top level
The idea is to float out bottoming expressions to top level,
abstracting them over any variables they mention, if necessary. This
is good because it makes functions smaller (and more likely to
inline), by keeping error code out of line.
See Note [Bottoming floats] in SetLevels.
On the way, this fixes the HPC failures for cg059 and friends.
I've been meaning to do this for some time. See Maessen's paper 1999
"Bottom extraction: factoring error handling out of functional
programs" (unpublished I think).
Here are the nofib results:

+1 s.d. ----- +2.3%
Average ----- -0.2%
Compile times:
-1 s.d. ----- -11.4%
+1 s.d. ----- +4.3%
Average ----- -3.8%
I'm think program sizes have crept up because the base library
is bigger -- module sizes in nofib decrease very slightly. In turn
I think that may be because the floating generates a call where
there was no call before. Anyway I think it's acceptable.
The main changes are:
* SetLevels floats out things that exprBotStrictness_maybe
identifies as bottom. Make sure to pin on the right
strictness info to the newly created Ids, so that the
info ends up in interface files.
Since FloatOut is run twice, we have to be careful that we
don't treat the function created by the first float-out as
a candidate for the second; this is what worthFloating does.
See SetLevels Note [Bottoming floats]
Note [Bottoming floats: eta expansion]
* Be careful not to inline top-level bottoming functions; this
would just undo what the floating transformation achieves.
See CoreUnfold Note [Do not inline top-level bottoming functions
Ensuring this requires a bit of extra plumbing, but nothing drastic..
* Similarly pre/postInlineUnconditionally should be
careful not to re-inline top-level bottoming things!

Make -ddump-simpl-stats a bit more informative by default
This mades -ddump-simpl-stats print out per-rule and per-id
information by default, rather than requiring -dppr-debug.
On the whole that is what you want. The -dppr-debug flag
now just controls printing of the log.

Fix #3741, simplifying things in the process
The problem in #3741 was that we had confused column numbers with byte
offsets, which fails in the case of UTF-8 (amongst other things).
Fortunately we're tracking correct column offsets now, so we didn't
have to make a calculation based on a byte offset. I got rid of two
fields from the PState (last_line_len and last_offs).and one field
from the AI (alex input) constructor.
