a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.

expected-foo strings.  Now the only allowed characters between 
expected-error and {{  is whitespace.

mangled, report it using the diagnostics machinery instead of printf.

"previously defined here" diagnostics all notes.

"definitions", not declarations.  Point out the location of the 
original definition.

Also, point out where the previous decl was.  This unxfails two tests.

with implicit quotes around them.  This has a bunch of follow-on 
effects and requires tweaking to a whole lot of code.  This causes
a regression in two tests (xfailed) by causing it to emit things like:

  Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')

instead of:

  Line 10: duplicate interface declaration for category 'MyClass1(Category1)'

I will fix this in a follow-up commit.

As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency.  This is good, but I was planning to do this
as an independent patch.  There will be several follow-on patches
to clean up some of the mess, but this patch is already too big.

without calling getAsString().  This implicitly puts quotes around the
name, so diagnostics need to be tweaked to accommodate this.

No functionality change.

diags over to use this.  QualTypes implicitly print single quotes around 
them for uniformity and future extension.

Doing this requires a little function pointer dance to prevent libbasic
from depending on libast.
