Changes many calls to normalize to dealiasWiden.
Calling normalize is very aggressive and is usually the wrong
thing. It is one of the leading contributors to non-determinism
in compiler outcomes (often of the form "I gave a debugging or
logging compiler option and it started/stopped working") and
should be used only in very specific circumstances.
Almost without exception, dealiasWiden is what you want; not
widen, not normalize. If possible I will remove normalize from
Type entirely, making it private to those areas of the compiler
which actually require it.
