Change Sema::CheckAddressOfOperation() to respect C99-only addressof rules.
...
Remove diagnostics from Sema::CheckIndirectionOperand(). C89/C99 allow dereferencing an incomplete type. clang appears to be emulating some incorrect gcc behavior (see below).
void
foo (void)
{
struct b;
struct b* x = 0;
struct b* y = &*x; // gcc produces an error ("dereferencing pointer to incomplete type")
}
With this patch, the above is now allowed.

Created ExplodedGraph.cpp and moved most method implementations of

ExplodedNodeImpl::NodeGroup from being defined inline to being defined
"out-of-line" in ExplodedGraph.cpp. This removes a dependence on including
<vector> in ExplodedGraph.h, and will hopefully result in smaller generated code
with negligible performance impact.

When forming the squigly underline for a diagnostic, make sure to

verify that the source range corresponds to the current file, not
just the current line. This allows us to emit:
a.c:1:44: error: invalid operands to binary expression ('double' and 'int *')
double a; int *b; void f(void) { int c = a +
~ ^
instead of:
a.c:1:44: error: invalid operands to binary expression ('double' and 'int *')
double a; int *b; void f(void) { int c = a +
~ ~ ^
