Fix bin-packing behavior of constructor initialziers.

In Google style, constructor initializers need to be all on one line or
one initializer per line if that does not fit. Without this patch, this
non-bin-packing-behavior incorrectly extends to the parameters of the
initializers.

Before:
Constructor()
    : aaaaa(aaaaaaaaaaaaaaaaaaaaaa,
            aaaaaaaaaaaaaaaaaaaaaa,
            aaaaaaaaaaaaaaaaaaaaaa) {}

After:
Constructor()
    : aaaaa(aaaaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaa,
            aaaaaaaaaaaaaaaaaaaaaa) {}

cmake: Only add -pedantic if LLVM didn't add it. Don't unconditionally add
-Wall -W, since it's already provided by LLVM's cmake config, and that
overrides fixes (such as -Wno-uninitialized) which LLVM's cmake setup may have
provided.

C++1y constexpr extensions, round 1: Allow most forms of declaration and
statement in constexpr functions. Everything which doesn't require variable
mutation is also allowed as an extension in C++11. 'void' becomes a literal
type to support constexpr functions which return 'void'.

TBAA: make sure zero-length bitfield works for tbaa.struct and path-aware tbaa

For ms structs, zero-length bitfields following non-bitfield members are
completely ignored, we should not increase the field index.
Before the fix, we will have an assertion failure.

[analyzer] Type information from C++ new expressions is perfect.

This improves our handling of dynamic_cast and devirtualization for
objects allocated by 'new'.

[analyzer] Treat reinterpret_cast like a base cast in certain cases.

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.

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).
