Steve Naroff 788d864d6c - Finish hooking up support for __builtin_types_compatible_p().
- Fix type printing code for recently added TypeOfExpr/TypeOfType.

Steve Naroff 7886467b35 Add AST/Sema support for __builtin_types_compatible_p (a GNU extension).
Todo...still need to call the action from the parser...

Steve Naroff a773cd5d15 Add comments to getTypeOfExpr/getTypeOfType.
Also add instances of TypeOfExpr/TypeOfType to the Types vector (so we can keep track of them).

Steve Naroff 236becbbc3 Two typeof() related changes...
- Changed the name of ASTContext::getTypeOfType(Expr*)->getTypeOfExpr().
- Remove FIXME for TypeOfExpr::getAsStringInternal(). This will work fine for printing the AST. It isn't ideal
for error diagnostics (since it's more natural to display the expressions type). 

One "random" (or at least delayed:-) change...

- Changed all "ext_typecheck_*" diagnostics from EXTENSION->WARNING. Reason: Since -pedantic is now
off (by default), these diagnostics were never being emitted (which is bad). With this change, clang will
emit the warning all the time. The only downside (wrt GCC compatibility) is -pedantic-errors will not turn
this diagnostics into errors (a "feature" of making tagging them with EXTENSION). When/if this becomes
an issue, we can revisit.

Chris Lattner fedeaa3045 Don't use canonical type for sema here. In
void func() {
typedef int foo;
foo *Y;
**Y; // error
}

we now get:
indirection requires pointer operand ('foo' invalid)
instead of:
indirection requires pointer operand ('int' invalid)

Steve Naroff ddf5a1d7a6 Implement pretty diagnostics when doing on-the-fly vector sizing (for vector component access).
For example, before this commit, the following diagnostics would be emitted...

ocu.c:49:12: error: incompatible types assigning 'float  __attribute__((ocu_vector_type(3)))' to 'float4'
    vec4_2 = vec4.rgb; // shorten
    ~~~~~~ ^ ~~~~~~~~
ocu.c:51:7: error: incompatible types assigning 'float  __attribute__((ocu_vector_type(2)))' to 'float'
    f = vec2.xx; // shorten
    ~ ^ ~~~~~~~

Now, the diagnostics look as you would expect...

ocu.c:49:12: error: incompatible types assigning 'float3' to 'float4'
    vec4_2 = vec4.rgb; // shorten
    ~~~~~~ ^ ~~~~~~~~
ocu.c:51:7: error: incompatible types assigning 'float2' to 'float'
    f = vec2.xx; // shorten
    ~ ^ ~~~~~~~

Steve Naroff 49ab97761b Fix the following bogus diagnostic...reported by Jeroen.
#include <stdio.h>

int
main(void) {
        int test = 0;

        printf("Type is %s\n", (test >= 1 ? "short" : "char"));

        return (0);
}

It comes up with a diagnostic that's misleading upon first read.

t.c:7:36: error: incompatible operand types ('char *' and 'char *')
        printf("Type is %s\n", (test >= 1 ? "short" : "char"));
                                          ^ ~~~~~~~   ~~~~~~

Steve Naroff 185616f293 Various improvements to Sema::ParseMemberReferenceExpr().
- Added source range support to Diag's.
- Used the new type predicate API to remove dealing with the canonical
type explicitly.

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.

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%
