Summary:
Added support for multiple input files, that can be used both with and
without in-place edit (-i) option. Added checks for -offset and -length options:
don't allow them on multiple files, check that they don't fall outside input
file, made both options unsigned, so that there's no need to check for negative
values. Removed "-1 can be used for end-of-file" from -length description.

 - If only partial invalidators exist and there are no full invalidators in @implementation, report every ivar that has
not been invalidated. (Previously, we reported the first Ivar in the list, which could actually have been invalidated
by a partial invalidator. The code assumed you cannot have only partial invalidators.)

- Do not report missing invalidation method declaration if a partial invalidation method declaration exists.

The uniqueing location is the location which is part of the hash used to determine if two reports are
the same. This is used by the CmpRuns.py script to compare two analyzer runs and determine which
warnings are new.

[analyzer] Refactor BugReport::getLocation and PathDiagnosticLocation::createEndOfPath for greater code reuse

The 2 functions were computing the same location using different logic (each one had edge case bugs that the other
one did not). Refactor them to rely on the same logic.

The location of the warning reported in text/command line output format will now match that of the plist file.

There is one change in the plist output as well. When reporting an error on a BinaryOperator, we use the location of the
operator instead of the beginning of the BinaryOperator expression. This matches our output on command line and
looks better in most cases.

When modifying an implicit instantiation with information from an explicit one, make sure to reset the "right brace" location.

Otherwise the source range of the explicit instantiation may become invalid (begin location will be after the end location).

The analyzer represents all pointer-to-pointer bitcasts the same way, but
this can be problematic if an implicit base cast gets layered on top of a
manual base cast (performed with reinterpret_cast instead of static_cast).
Fix this (and avoid a valid assertion) by looking through cast regions.

Using reinterpret_cast this way is only valid if the base class is at the
same offset as the derived class; this is checked by -Wreinterpret-base-class.
In the interest of performance, the analyzer doesn't repeat this check
anywhere; it will just silently do the wrong thing (use the wrong offsets
for fields of the base class) if the user code is wrong.

non-bin-packing-behavior incorrectly extends to the parameters of the
initializers.
