Incomplete work to upgrade Idris to 1.2.0

Hello all,

This is my attempt to upgrade Idris to 1.2.0, the version included in
LTS Haskell 10.7. sclv on #hackage helped me figure out that one of the
remaining problems is a version mismatch on ghc-binary:

    $ ./pre-inst-env guix build idris
    ...
    Warning: This package indirectly depends on multiple versions of the same
    package. This is highly likely to cause a compile failure.
    package zip-archive-0.3.0.5 requires binary-0.8.3.0
    package vector-binary-instances-0.2.4 requires binary-0.8.3.0
    package uuid-types-1.0.3 requires binary-0.8.3.0
    package text-1.2.2.2 requires binary-0.8.3.0
    package scientific-0.3.5.2 requires binary-0.8.3.0
    package idris-1.2.0 requires binary-0.8.5.1
    ...
    [ 23 of 114] Compiling Idris.Core.Binary ( src/Idris/Core/Binary.hs, dist/build/Idris/Core/Binary.o )

    src/Idris/Core/Binary.hs:233:10: error:
        ? No instance for (Binary Data.Text.Internal.Text)
            arising from a use of ?binary-0.8.5.1:Data.Binary.Class.$dmput?
        ? In the expression: binary-0.8.5.1:Data.Binary.Class.$dmput @Name
        In an equation for ?put?:
            put = binary-0.8.5.1:Data.Binary.Class.$dmput @Name
        In the instance declaration for ?Binary Name?
    ...

It seems like ghc-text uses the GHC-bundled version of binary:

    $ ./pre-inst-env guix environment idris -- ghc-pkg list
    ...
    /gnu/store/gvqz0x4n15zgdqnh5z675ca97j1si766-profile/lib/ghc-8.0.2/ghc-text-1.2.2.2.conf.d
        array-0.5.1.1
        base-4.9.1.0
        binary-0.8.3.0
        bytestring-0.10.8.1
        containers-0.5.7.1
        deepseq-1.4.2.0
        ghc-prim-0.5.0.0
        integer-gmp-1.0.0.1
        rts-1.0
        text-1.2.2.2
    ...

I tried adding ghc-binary (our ghc-binary is at 0.8.5.1, which should
agree with Irdris's) to the inputs of ghc-text, but it appears to cause
a circular dependency -- guix-building idris or ghc-text after this
modification causes a heap OoM in Guile.

I would appreciate any pointers about what I can try next! :)

Subject: [PATCH] (WIP) gnu: idris: Upgrade to 1.2.0.

* gnu/packages/idris.scm (idris): upgrade to 1.2.0. [inputs] alphebetize
  ghc-vector-binary-instances and ghc-async. Delete ghc-parsers, ghc-tasty,
  ghc-tasty-golden, ghc-tasty-rerun, ghc-trifecta, and ghc-zlib as they are
  not dependencies of 1.2.0. Add ghc-binary and ghc-megaparsec.
