Import ghc-7.6.3 as lang/ghc7.

Based on wip/ghc, mostly worked by phonohawk, with patches from jperkin@.
And some modifications and buit of Bootstrap binaries for 7.6.3 by me.

GHC: The Glasgow Haskell Compiler.

The Glasgow Haskell Compiler is a robust, fully-featured, optimising
compiler for the functional programming language Haskell 98
(http://www.haskell.org). GHC compiles Haskell to either native code
or C. It implements numerous experimental language extensions to
Haskell, including concurrency, a foreign language interface, several
type-system extensions, exceptions, and so on. GHC comes with a
generational garbage collector, a space and time profiler, and a
comprehensive set of libraries.

+# GHC requires GHC to build itself. Formerly we could work around this
+# bootstrapping problem by creating a special archive containing C
+# sources compiled from Haskell sources, but that's no longer
+# possible. So we have to prepare stripped-down binaries sufficient to
+# bootstrap compilers for each platforms. If you want to build them
+# yourself, follow an instruction in the ./TODO file.
