This reorganization allows adding attributes that refer to types.
I need this for a @_specialize attribute with a type list.
PrintOptions.h and other headers depend on these enums. But Attr.h
defines a lot of classes that almost never need to be included.
avoid emitting this diagnostics. They are always irritating to it because they
are duplicative with whatever the actual type constraint problem is. It also
interferes with there recursive structure of the problem.
Disabling them also allows us to shorten the black list of expr nodes that cannot
be handled in typeCheckIndependentSubExpression.

<rdar://problem/15975935> warning that you can use 'let' not 'var'
<rdar://problem/18876585> Compiler should warn me if I set a parameter as 'var' but never modify it
<rdar://problem/17224539> QoI: warn about unused variables
This uses a simple pass in MiscDiagnostics that walks the body of an
AbstractFunctionDecl. This means that it doesn't warn about unused properties (etc),
but it captures a vast majority of the cases.
It also does not warn about unused parameters (as a policy decision) because it is too noisy,
there are a variety of other refinements that could be done as well, thoughts welcome.

There's no meaningful way in which these methods are public, since they
can't be accessed through any value of the type

We still want to allow line wrapping, so only issue the warning when the indentation of the expression and the return keyword is the same.

rdar://14151649 suggests that it should be a warning, but I don’t see a reason
why it should not be an error. We have no legacy code that relies on this.
