Run codegen dce pass for all targets at all optimization levels. Previously it's
...
only run for x86 with fastisel. I've found it being very effective in
eliminating some obvious dead code as result of formal parameter lowering
especially when tail call optimization eliminated the need for some of the loads
from fixed frame objects. It also shrinks a number of the tests. A couple of
tests no longer make sense and are now eliminated.

Don't enable the post-RA scheduler on x86 except at -O3. In its
...
current form, it is too expensive in compile time.

Fix a couple of shuffle patterns to use movhlps instead
...
of movhps as the constraint. Changes optimizations so
update testcases as appropriate as well.

change selectiondag to add the sign extended versions of immediate operands
...
to instructions instead of zero extended ones. This makes the asmprinter
print signed values more consistently. This apparently only really affects
the X86 backend.
