[analyzer] Fix static_cast on pointer-to-member handling
This commit fixes bug #48739. The bug was caused by the way static_casts
on pointer-to-member caused the CXXBaseSpecifier list of a
MemberToPointer to grow instead of shrink.
The list is now grown by implicit casts and corresponding entries are
removed by static_casts. No-op static_casts cause no effect.

[analyzer] Fix crash with pointer to members values
This fix unifies all of the different ways we handled pointer to
members into one. The crash was caused by the fact that the type
of pointer-to-member values was `void *`, and while this works
for the vast majority of cases it breaks when we actually need
to explain the path for the report.

Revert "[analyzer] pr38668: Do not attempt to cast loaded values..."
This reverts commit r349701.
The patch was incorrect. The whole point of CastRetrievedVal()
is to handle the case in which the type from which the cast is made
(i.e., the "type" of value `V`) has nothing to do with the type of
the region it was loaded from (i.e., `R->getValueType()`).

[analyzer] pr38668: Do not attempt to cast loaded values of non-scalar types.
It is expected to have the same object (memory region) treated as if it has
different types in different program points.
[analyzer] pr38668: Do not attempt to cast loaded values of non-scalar types.
It is expected to have the same object (memory region) treated as if it has
different types in different program points. The correct behavior for
RegionStore when an object is stored as an object of type T1 but loaded as
an object of type T2 is to store the object as if it has type T1 but cast it
to T2 during load.
Note that the cast here is some sort of a "reinterpret_cast" (even in C). For
instance, if you store a float and load an integer, you won't have your float
rounded to an integer; instead, you will have garbage.
Admit that we cannot perform the cast as long as types we're dealing with are
non-trivial (neither integers, nor pointers).
Of course, if the cast is not necessary (eg, T1 == T2), we can still load the
value just fine.

[analyzer] For now, treat pointers-to-members as non-null void * symbols.
Until we have full support for pointers-to-members, we can at least

We thus treat &A::m_ptr as a non-null void * symbol, and MemberPointer(0)
as a pointer-sized null constant.
This enables support for what is sometimes called the "safe bool" idiom,
demonstrated in the test case.
