Reland 4: [analyzer] NFC: Update test infrastructure to support multiple constraint managers
...
Summary: Replace calls to %clang/%clang_cc1 with %clang_analyze_cc1 when invoking static analyzer, and perform runtime substitution to select the appropriate constraint manager, per D28952.

[analyzer] Let TK_PreserveContents span across the whole base region.
...
If an address of a field is passed through a const pointer,
the whole structure's base region should receive the
TK_PreserveContents trait and avoid invalidation.
Additionally, include a few FIXME tests shown up during testing.

[analyzer] Functions marked __attribute__((const)) don't modify any memory.
...
This applies to __attribute__((pure)) as well, but 'const' is more interesting
because many of our builtins are marked 'const'.

[analyzer] Invalidate regions indirectly accessible through const pointers.
...
In this case, the value of 'x' may be changed after the call to indirectAccess:
struct Wrapper {
int *ptr;
};
void indirectAccess(const Wrapper &w);
void test() {
int x = 42;
Wrapper w = { x };
clang_analyzer_eval(x == 42); // TRUE
indirectAccess(w);
clang_analyzer_eval(x == 42); // UNKNOWN
}
This is important for modelling return-by-value objects in C++, to show
that the contents of the struct are escaping in the return copy-constructor.
