Change Expr::isLvalue() to allow the "void" type. This fixes bz2000 submitted by Neil Booth.

Neil, can you point me to the place in the C99 spec that says this is allowed? I thought Expr::isLvalue() conformed to the spec, which says "C99 6.3.2.1: an lvalue is an expression with an object type or an incomplete type other than void.". Please advise.

common problem of putting two terminators in the same block.  I can't write
a testcase for this because the .ll parser rejects this before the verifier
can, but this can occur when generating IR.

A bunch-o changes to fix <rdar://problem/5716046> incomplete implementation of ObjC class warning is incomplete

As part of this fix, I made a low-level change to the text diagnostics machinery (to basically avoid printing duplicate source lines/carets when you have multiple diagnostics that refer to the same exact place). For now, this only happens with we don't have a source range (could be extended to support source ranges as well).

Support fuzzy parsing MS line-oriented __asm's that originate from a macro (a case where we can't obtain source line info). As the test case indicates, we don't currently support line-oriented asm statements that mix file/macro body tokens.
