Deprecate ports that don't build with recent GHC version

lang/ghc: Update to 8.4.3 and bump PORTREVISION's of all Haskell ports.

As usual, it is recommended to rebuild or reinstall all the
dependent ports and the lang/ghc port itself in one of the following
ways:

# portmaster -w -r ghc
  or
# portupgrade -fr lang/ghc

In case of pkg(8), it is probably safer to remove all the GHC-dependent
packages along with GHC and reinstall everything from scratch.  For
example:

# pkg query "%ro" ghc > ghc-pkgs.txt
# pkg delete -y lang/ghc

In ghc-pkgs.txt, check and remove all the packages that have been moved
on the update, then use this command:

# pkg install -y `cat ghc-pkgs.txt`

Thanks a lot to arrowd for doing all the heavy lifting :)

Switch C compiler used to compile GHC to base Clang.

This removes build dependency on gcc and runtime dependency on gcc's runtime
libraries.

Big thanks to Gleb for working on this.

Update to libmpc version 1.0.1 which brings the following fixes:

 - Switched to automake 1.11.6, see CVE-2012-3386.
 - #14669: Fixed extraction of CC from gmp.h.
 - Fixed case of intermediate zero real or imaginary part in mpc_fma,
   found by hydra with GMP_CHECK_RANDOMIZE=1346362345.

This is on top of the following changes from version 1.0

 - Licence change towards LGPLv3+ for the code and GFDLv1.3+ (with no
   invariant sections) for the documentation.
 - 100% of all lines are covered by tests
 - Renamed functions
   . mpc_mul_2exp to mpc_mul_2ui
   . mpc_div_2exp to mpc_div_2ui

Add NO_STAGE all over the place in preparation for the staging support (cat:
devel part 2)

Some highlights of the update:

- Fix PDF generation for pandoc [1]
- From now on, PREFIX/{lib,share,share/doc}/cabal/ghc-GHC_VERSION are used for
  hs- ports (Cabal packages) as prefixes to avoid problems when upgrading with
  portmaster(8) [2]
- Experimental support for LLVM-based code generation (disabled by default)
- Many simplifications, refactoring in bsd.cabal.mk

- Fix breakage in the DYNAMIC-enabled ports triggered by the recent
  devel/libffi update
- Enable multithreaded build for lang/ghc (i.e. mark MAKE_JOBS_SAFE)

Bump PORTREVISION of all ports dependent on lang/ghc as during
upgrade, lang/ghc cabal package cache gets invalidated causing all
dependent ports to be reinstalled.

Typical buffer-based incremental I/O is based around a single loop,
which reads data from some source (such as a socket or file), transforms
it, and generates one or more outputs (such as a line count, HTTP
responses, or modified file). Although efficient and safe, these loops are
all single-purpose; it is difficult or impossible to compose
buffer-based processing loops.

Haskell's concept of "lazy I/O" allows pure code to operate on data from an
external source. However, lazy I/O has several shortcomings. Most notably,
resources such as memory and file handles can be retained for arbitrarily
long periods of time, causing unpredictable performance and error conditions.

Enumerators are an efficient, predictable, and safe alternative to lazy
I/O. Discovered by Oleg Kiselyov, they allow large datasets to be processed
in near constant space by pure code. Although somewhat more complex
to write, using enumerators instead of lazy I/O produces more correct
programs.

This library contains an enumerator implementation for Haskell, designed to
be both simple and efficient.
