Use std::map instead of a (potentially very sparse) array to track val# defined by copy from the other live range. Minor compile time win when number of val# is large.

to their corresponding library routines (e.g. isinf).  This allows us to handle
all the stuff in macos math.h, and other stuff as it's added to *Builtins.def.

Use APFloat interfaces for more references, mostly
of ConstantFPSDNode.

The following case now works...

void empty(void * a ) {}

void test()
{
    unsigned char A[4]; 
    empty( (void *) A); 
}

Thanks to Patrick Flannery for finding this...

Comments added. It now generates V5TE multiply instructions. However, it is still necessary to model PUWLSH bits more clearly.

Final phase of array cleanup (for now), removing a FIXME from yesterday.

Moved several array constraints checks from Sema::VerifyConstantArrayType() to
Sema::GetTypeForDeclarator(). VerifyConstantArrayType() is now very simple, and
could be removed eventually.

Now, we get the following (correct) messages for BlockVarDecls:-)

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang x.c -pedantic

introduced by moving "CaseStmt" pointers out of the list of statements
and into the explicit "label" associated with a CFGBlock.  --This
line, and those below, will be ignored--

no statements (or just full of ';' statements).

llvm-svn: 41620

blocks involving only ';' statements.  We now correctly handle the following:

void empty_label() { l1: ; }

llvm-svn: 41619

llvm-svn: 41618

an empty then or else block (or contained only ';' statements).

For example, we now handle the following:

int empty_else() { if (0) { int a; } else ; }
int empty_then() { if (0) ; else { int a; } }

Thanks to Nico Weber for spotting this problem.

Refactored Array/VariableArray, moving SizeModifier/IndexTypeQuals back up to Array. These
attributes are not specific to VLA's. Most of them are specific to array parameter types.

including the expressions in the case statement itself (not the body of
the case).

This required moving SubStmt out of SwitchCase into CaseStmt and DefaultStmt
respectively.  getSubStmt() now is a virtual call for SwitchCase, but is
a direct (static) call for CaseStmt and DefaultStmt.

For example, -parse-ast-dump now prints:

static inline int __inline_isinff(float __x)
(CompoundStmt 0x2409a20
  (ReturnStmt 0x2409a10
    (BinaryOperator 0x24099f0 'int' <///usr/include/architecture/i386/math.h:183:63, col:102> '=='
      (CallExpr 0x24098f0 'float' <col:63, col:82>
        (ImplicitCastExpr 0x24098e0 'float (*)(float)' <col:63>
          (DeclRefExpr 0x2409880 'float (float)' <col:63> Decl='__builtin_fabsf' 0x2409840))
        (DeclRefExpr 0x24098a0 'float' <col:79> Decl='__x' 0x2409810))
      (CallExpr 0x24099c0 'float' <col:87, col:102>
        (ImplicitCastExpr 0x2409870 'float (*)(void)' <col:87>
          (DeclRefExpr 0x2409980 'float (void)' <col:87> Decl='__builtin_inff' 0x2409940))))))

where it only prints filename/line# if it changes from the previous value.  We 
really need loc info on stmts though, like we have on exprs.
