[analyzer] Use the new registration mechanism on some of the experimental checks. These are:
...
CStringChecker
ChrootChecker
MallocChecker
PthreadLockChecker
StreamChecker
UnreachableCodeChecker
MallocChecker creates implicit dependencies between checkers and needs to be handled differently.

Casting to void* or any other pointer-to-sizeless type (e.g. function pointers) causes a divide-by-zero error. Simple fix: check if the pointee type size is 0 and bail out early if it is.

CastSizeChecker checks when casting a malloc'ed symbolic region to type T,

whether the size of the symbolic region is a multiple of the size of T.

Add new states for symbolic regions tracked by malloc checker. This enables us
to do malloc checking more accurately. See test case.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
