New codegen: GC calling convention must use registers.
Previously, on register-deficient architectures like x86-32,
the new code generator would emit code for calls to stg_gc_l1,

Fix an egregious strictness analyser bug (Trac #4924)
The "virgin" flag was being threaded rather than treated
like an environment. As a result, the second and subsequent
recursive definitions in a module were not getting a
correctly-initialised fixpoint loop, causing much worse
strictness analysis results. Indeed the symptoms in
Trac #4924 were quite bizarre.
Anyway, it's easily fixed. Merge to stable branch.

Refine incomplete-pattern checks (Trac #4905)
The changes are:
* New flag -fwarn-incomplete-uni-patterns, which checks for
incomplete patterns in (a) lambdas, (b) pattern bindings
* New flag is not implied by -W or -Wall (too noisy; and many
libraries use incomplete pattern bindings)
* Actually do the incomplete-pattern check for pattern bindings
(previously simply omitted)
* Documentation for new flag

Fix "make 1" etc following the build system changes
The logic is now in mk/compiler-ghc.mk rather than being duplicated in
ghc/Makefile and compiler/Makefile.
