Chris Lattner 02c0439a44 Fix a couple of bugs, add some new cool stuff. 
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.

Steve Naroff 44fd8ff400 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);
        ~~~~~~~~~~~~~~ ^~~~
test/Parser/promote_types_in_proto.c:8:27: error: incompatible types passing 'void (char *const [])' to function expecting 'void (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.

Anton Korobeynikov 0c46451d2b Heal EH handling stuff by emitting correct offsets to callee-saved registers. 
Pretty hackish, but code itself is dirty mess, so we won't make anything worse. :)

Chris Lattner 4c4a245475 Use a smallstring instead of an std::string in FileChanged to avoid some malloc traffic. 
This speeds up -E on xalancbmk by 2.4%

Chris Lattner 8996ffffe5 Add a cache to SourceManager to accellerate line # lookup. This is a 
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.

This speeds up -E on xalancbmk by 3.2%

Reid Spencer 6c2b393f0c Add better verification of attributes on function types. It is not permitted 
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.
