Remove hack from LiveVariables analysis where variables whose address are taken
...
are considered 'live'. This hack isn't needed anymore because we have a
separation in the path-sensitive analyzer between variable names and bindings;
the analyzer can continue to reason about the storage of a variable after its
name is no longer directly referenced. Now the live variables analysis literally means "is this name live".
Along this line, update the dead stores checker to explicitly look for variables
whose values have escaped.

When calling a function without a prototype for which we have a
...
definition, warn if there are too many/too few function call
arguments.

Also "flatten" PathLocations fed to the HTMLDiagnosticClient. We need a better
...
long-term strategy, but this should work for now.

Hack: Add 'PathDiagnostic::flattenLocations()'. Because PlistDiagnosticClient
...
can use a PathLocation after any reference Stmts are reclaimed,
flattenLocation() converts those references to statements to source ranges.

fix a FIXME, providing accurate source range info for DeclStmt's. The end
...
of the range is now the ';' location. For something like this:
$ cat t2.c
#define bool int
void f(int x, int y) {
bool b = !x && y;
}
We used to produce:
$ clang-cc t2.c -ast-dump
typedef char *__builtin_va_list;
void f(int x, int y)
(CompoundStmt 0x2201f10 <t2.c:3:22, line:5:1>
(DeclStmt 0x2201ef0 <line:2:14> <----
0x2201a20 "int b =
(BinaryOperator 0x2201ed0 <line:4:10, col:16> 'int' '&&'
(UnaryOperator 0x2201e90 <col:10, col:11> 'int' prefix '!'
(DeclRefExpr 0x2201c90 <col:11> 'int' ParmVar='x' 0x2201a50))
(DeclRefExpr 0x2201eb0 <col:16> 'int' ParmVar='y' 0x2201e10))")
Now we produce:
$ clang-cc t2.c -ast-dump
typedef char *__builtin_va_list;
void f(int x, int y)
(CompoundStmt 0x2201f10 <t2.c:3:22, line:5:1>
(DeclStmt 0x2201ef0 <line:2:14, line:4:17> <------
0x2201a20 "int b =
(BinaryOperator 0x2201ed0 <col:10, col:16> 'int' '&&'
(UnaryOperator 0x2201e90 <col:10, col:11> 'int' prefix '!'
(DeclRefExpr 0x2201c90 <col:11> 'int' ParmVar='x' 0x2201a50))
(DeclRefExpr 0x2201eb0 <col:16> 'int' ParmVar='y' 0x2201e10))")
