Choose external names more predictably
Now, for a compiler-generated binding "x", if "x" is referred to by
the exported "f", then it will be named "f_x" rather than something
like "x23". This means that hopefully
- compilation will more often product the same results given the
same input (the choice of names is not dependent on the
non-deterministic order of bindings within the compiler).
- less recompilation will be necessary after making changes
- navigating Core might be a bit easier.
unfortunately, compilation with -O still does not consistently produce
the same ABI. The simplifier sometimes does different things,
apparently.

Use names like '$fOrdInt' for dfuns (and TF instances), rather than '$f21'
2 reasons for this:
- compilation is more predictable. Adding or removing an instance
is less likely to force unnecessary recompilation due to
renumbering other dfun names.
- it makes it easier to read Core / C-- / asm
The names aren't completely deterministic. To do that, we'd have to
include package and module names, which would make the symbol names
long and reduce readability. So the compromise is that if there's a
clash, we disambiguate by adding an integer suffix. This is fairly
unlikely in practice unless you're using overlapping instances.

disambiguation strategy.

New syntax for GADT-style record declarations, and associated refactoring
The main purpose of this patch is to fix Trac #3306, by fleshing out the
syntax for GADT-style record declraations so that you have a context in

data T a where
MkT :: forall a. Eq a => { x,y :: !a } -> T a
See discussion on the Trac ticket.
The old form is still allowed, but give a deprecation warning.
When we remove the old form we'll also get rid of the one reduce/reduce
error in the grammar. Hurrah!
While I was at it, I failed as usual to resist the temptation to do lots of
refactoring. The parsing of data/type declarations is now much simpler and
more uniform. Less code, less chance of errors, and more functionality.
Took longer than I planned, though.
ConDecl has record syntax, but it was not being used consistently, so I
pushed that through the compiler.
