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.

Enable the new no-SP register classes by default. This is to address
...
PR4572. A few tests have some minor code regressions due to different
coalescing.
