[ms-inline asm] Add a very simple test case. Basically, we're only testing for
crashers at the moment (and coincidentally this case was causing a crash).

Add test triples to fix win32 failures. Revert workaround from r161292.
I don't have a win32 system to test, so hopefully I got them all fixed here.

Remove OpenBSD defines:
- The defines are in stddint.h, which is #include'd already.
- The block wasn't used anyway, since it was _OpenBSD_, and not __OpenBSD__

[analyzer] Clean up the printing of FieldRegions for leaks.
Unfortunately, generalized region printing is very difficult:
- ElementRegions are used both for casting and as actual elements.
- Accessing values through a pointer means going through an intermediate
SymbolRegionValue; symbolic regions are untyped.
- Referring to implicitly-defined variables like 'this' and 'self' could be
very confusing if they come from another stack frame.
We fall back to simply not printing the region name if we can't be sure it
will print well. This will allow us to improve in the future.

[analyzer] Track malloc'd regions stored in structs.
The main blocker on this (besides the previous commit) was that
ScanReachableSymbols was not looking through LazyCompoundVals.
Once that was fixed, it's easy enough to clear out malloc data on return,
just like we do when we bind to a global region.
