<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Improve parser error messages for the @-operator

Since GHC diverges from the Haskell Report by allowing the user

to define (@) as an infix operator, we better give a good

error message when the user does so unintentionally.

In general, this is rather hard to do, as some failures will be

discovered only in the renamer or the type checker:

        x :: (Integer, Integer)

        x @ (a, b) = (1, 2)

This patch does *not* address this general case.

However, it gives much better error messages when the binding

is not syntactically valid:

        pairs xs @ (_:xs') = zip xs xs'

Before this patch, the error message was rather puzzling:

        <interactive>:1:1: error: Parse error in pattern: pairs

After this patch, the error message includes a hint:

        <interactive>:1:1: error:

            Parse error in pattern: pairs

            In a function binding for the ‘@’ operator.

            Perhaps you meant an as-pattern, which must not be surrounded by whitespace

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Improve parser error messages for TypeApplications

With this patch, we always parse  f @t  as a type application,

thereby producing better error messages.

This steals two syntactic forms:

* Prefix form of the @-operator in expressions. Since the @-operator is

  a divergence from the Haskell Report anyway, this is not a major loss.

* Prefix form of @-patterns. Since we are stealing loose infix form

  anyway, might as well sacrifice the prefix form for the sake of much

  better error messages.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Improve parser error messages for TemplateHaskellQuotes

While [e| |], [t| |], [d| |], and so on, steal syntax from list

comprehensions, [| |] and [|| ||] do not steal any syntax.

Thus we can improve error messages by always accepting them in the

lexer. Turns out the renamer already performs necessary validation.
