CLC proposals 231 and 261:
- Add exception type metadata to SomeException's displayException.
- Add "Exception" header to default exception handler.

This patch extends the grammar of expressions with syntax that is
typically found only in types:
* function types (a -> b), (a ->. b), (a %m -> b)
* constrained types (ctx => t)
* forall-quantification (forall tvs. t)
The new forms are guarded behind the RequiredTypeArguments extension,
as specified in GHC Proposal #281. Examples:
{-# LANGUAGE RequiredTypeArguments #-}
e1 = f (Int -> String) -- function type
e2 = f (Int %1 -> String) -- linear function type
e3 = f (forall a. Bounded a => a) -- forall type, constraint
The GHC AST and the TH AST have been extended as follows:
syntax | HsExpr | TH.Exp
---------------+----------+--------------
a -> b | HsFunArr | ConE (->)
a %m -> b | HsFunArr | ConE FUN
ctx => t | HsQual | ConstrainedE
forall a. t | HsForAll | ForallE
forall a -> t | HsForAll | ForallVisE
Additionally, a new warning flag -Wview-pattern-signatures has been
introduced to aid with migration to the new precedence of (e -> p :: t).

This commit adds support for multiline strings, proposed at
https://github.com/ghc-proposals/ghc-proposals/pull/569.
Multiline strings can now be written as:
myString =
"""
this is a
multiline string
"""
The multiline string will have leading indentation stripped away.
Full details of this post-processing may be found at the new
GHC.Parser.String module.
In order to cleanly implement this and maximize reusability, I
broke out the lexing logic for strings out of Lexer.x into a
new GHC.Parser.String module, which lexes strings with any
provided "get next character" function. This also gave us the
opportunity to clean up this logic, and even optimize it a bit.
With this change, parsing string literals now takes 25% less
time and 25% less space.

This commit generalises the infrastructure used for diagnostic codes,
allowing it to be used for other namespaces than the GHC namespace.
In particular, this enables GHCi to re-use the same infrastructure to
emit error messages.
