first wave of fixes for @encode sema support. This is part of PR3648.

The big difference here is that (like string literal) @encode has
array type, not pointer type.

Improve merging of function declarations. Specifically:
...
- When we are declaring a function in local scope, we can merge with
a visible declaration from an outer scope if that declaration
refers to an entity with linkage. This behavior now works in C++
and properly ignores entities without linkage.
- Diagnose the use of "static" on a function declaration in local
scope.
- Diagnose the declaration of a static function after a non-static
declaration of the same function.
- Propagate the storage specifier to a function declaration from a
prior declaration (PR3425)
- Don't name-mangle "main"
