New library fixup

I dunno whether this is correct, but it seems now if you write "-0.0"
in your source code as a Float and show it, you get "-0.0" back out
again (the previous sample output just had "0.0").  Looks fairly
harmless and/or more correct to me.

rank-n tests

Add 64 to the list of arguments to the bit operations in this test.

Turn this .hi file into an .hi-boot file

whoever wrote this test apparently got mixed up between '50' and
'500', so add the missing imports and add {-# SOURCE #-} while I'm here.

use {-# SOURCE #-} imports for the hand-written iface

use {-# SOURCE #-} imports for the hand-written ifaces

we don't support hand-written .hi files any more, so make this one an
.hi-boot file.

update expected output

new-library update

This test doesn't need to import PrelGHC at all

PrelGHC ==> GHC.Prim

update expected output

restore a couple of '-package lang's that seem to have gone missing

This test now aborts with a BlockedOnDeadMVar exception, not a deadlock.

Add a test description

update tests; cg029 moved to ccall/should_run, and cg030 is removed
(test case is already covered by other tests in ccall).

This test was previously codeGen/should_run/cg029, now updated to use
the FFI and moved to the right place.

update tests

PrelGHC ==> GHC.Exts

Passing a Float to a varargs C function isn't possible, so pass a
Double instead.

update tests

update to use new libraries and non-deprecated features

Add test for passing float args to a C function through the FFI.

Test inspired by Ralf Laemmel

The foreign import in here should be "safe" not "unsafe", because it
calls directly back to a foreign export.

missed the stderr file

A test for zero-constructor types

More tests

more import wibble

make them compile again

new-library-ise

Fix those failures which are manifestly due to the new library.

new-library-ise some of these

Move towards new-library-compatibility

new-library-ise

Catch up with changes in other parts of the tree

Add test for PAP_entry: CATCH_FRAME bug.

Check a difficult operator precedence case: (-3 **) where (**) is
infixl 7 should be disallowed.
