It's now just 'dopt Opt_Ticky'

We used to use a list lookup that couldn't fail. Now we just use
functions.

There were 3 overlapping entries for WayPar; I've commented out the ones
that were shadowed for now.

(fixes dyn tests with -fnew-codegen on x86)

Fixes cgrun071 on recent Mac OS X versions.

This is the right fix at least until we have proper types for Word8#,
Word16# etc.

This caused the CAF analysis to occasionally miss a CAF sometimes,
resulting in a very hard to diagnose crash.

This change means that we don't recover from erroneous type
declarations, thereby reporting fewer errors.  But trying to
recover confused GHC (leading to a pattern match failure in
the compiler Trac #7175), and it turned out to be tricky
to fix that.

So this patch takes the more conservative path of failing
earlier, perhaps reporting fewer real errors.

Pls merge to 7.6

I changed the behaviour slightly, e.g. i386/FreeBSD will no longer
fall through and use the Linux "i386-pc-linux-gnu", but will get the
final empty case instead. I assume that that's the right thing to do.

HaskellMachRegs.h is no longer included in anything under compiler/

Also, includes/CodeGen.Platform.hs now includes "stg/MachRegs.h"
rather than <stg/MachRegs.h> which means that we always get the file
from the tree, rather than from the bootstrapping compiler.
