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.

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 []'

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.
