1. Fix a todo in Parser::ParseTag, to recover better.  On code like
   that in test/Sema/decl-invalid.c it causes us to return a single
   error instead of multiple.
2. Fix an error in Sema::ParseDeclarator, where it would crash if the
   declarator didn't have an identifier.  Instead, diagnose the problem.
3. Start adding infrastructure to track the range of locations covered
   by a declspec or declarator.  This is mostly implemented for declspec,
   but could be improved, it is missing for declarator.

Thanks to Neil for pointing out this crash.

Fix Sema::ParseCallExpr()...it wasn't doing the default array/function promotions on it's argument types.

This resulted in the following errors when compiling promote_types_in_proto.c test...

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang test/Parser/promote_types_in_proto.c 
test/Parser/promote_types_in_proto.c:7:24: error: incompatible types passing 'char *[]' to function expecting 'char *const []'
        arrayPromotion(argv);

        functionPromotion(arrayPromotion);
        ~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~
2 diagnostics generated.

When fixing this, noticed that both ParseCallExpr() and ParseReturnStmt() were prematurely comparing types for
equivalence. This is incorrect (since the expr. promotions haven't been done yet). To fix this, I moved the
check "down" to Sema::CheckAssignmentConstraints().

I also converted Type::isArrayType() to the modern API (since I needed it). Still more Type predicates to 
convert.

bottleneck for -E computation, because every token that starts a line needs
to determine *which* line it is on (so -E mode can insert the appropriate 
vertical whitespace).  This optimization improves this common case where
it is striding through the line # table.

to use sret or inreg on the function. It is equally illegal to use noreturn
or nounwind on a parameter; they only go with the function. This patch
enforces these rules.
