declarations of same, introduce a single AST class and add appropriate bits
(encoded in the namespace) for whether a decl is "real" or not.  Much hackery
about previously-declared / not-previously-declared, but it's essentially
mandated by the standard that friends alter lookup, and this is at least
fairly non-intrusive.

Refactor the Sema methods specific to friends for cleaner flow and less nesting.

Incidentally solve a few bugs, but I remain confident that we can put them back.

Also, all one of the file level flags are implemented.

 - I'm still trying to figure out the cleanest way to implement this and match the assembler, currently there are some substantial differences.

pointers.  Most logic cares first about whether or not a region is
symbolic, and second if represents code.  This should fix a series of
silent corner case bugs (as well as simplify a bunch of code).

It also makes the llvmCore build dependent on whatever version of llvm-gcc
happens to be installed on the build machine.
