This avoids debuggers stepping to strange places (like the last

This is not the whole answer, though - similar bugs no doubt exist in
other loops (patches to follow) and attributing exception handling code

Make sure CallExpr::getLocStart doesn't segfault
Summary:
When the CallExpr passed to Sema::ConvertArgumentsForCall has all default parameters, and the number of actual arguments passed is zero, this function will segfault in the call to Call->getLocStart() if the Callee has an invalid getLocStart(), the reason being that since ConvertArgumentsForCall has set the correct number of arguments, but has not filled them in yet, getLocStart() will try to access the first (not yet existent) argument and thus segfaults.
This fixes that by making getLocStart return an invalid source location if the queried argument is NULL rather than segfaulting.

Limit our MSVC compat hack for nested names from dependent bases
Previously, any undeclared unqualified id starting a nested name
specifier in a dependent context would have its lookup retried during
template instantiation. Now we limit that retry hack to methods of a
class with dependent bases. Free function templates in particular are
no longer affected by this hack.
Also, diagnose this as a Microsoft extension. This has the downside that
template authors may see this warning *and* an error during
instantiation time about this identifier. Fixing that will probably
require formalizing some kind of "delayed" identifier, instead of our
ad-hoc solutions of forming dependent AST nodes when lookup fails.

CodeGen: When bitfields fall on natural boundaries, split them up
Currently when laying out bitfields that don't need any padding, we
represent them as a wide enough int to contain all of the bits. This
can be hard on the backend since we'll do things like represent stores
to a few bits as loading an i144, masking it with a large constant,
and storing it back.
This turns up in less pathological cases where we load and mask 64 bit
word on a 32 bit platform when we actually only need to access 32 bits.
This leads to bad code being generated in most of our 32 bit backends.
In practice, there are often natural breaks in bitfields, and it's a
fairly simple and effective heuristic to split these fields into legal
integer sized chunks when it will be equivalent (ie, it won't force us
to add any extra padding).

[modules] When we merge together multiple class template specialization
definitions (because some other declaration declares a special member that
isn't present in the canonical definition), we need to search *all* of them; we
can't just stop when we find the requested name in any of the definitions,
because that can fail to find things (and in particular, it can fail to find
the member of the canonical declaration and return a bogus ODR failure).

Correctly implement -include search logic.
According to the gcc docs, -include uses the current working directory
for the lookup instead of the main source file.
This patch gets rid of NormalizeIncludePath (which relied on an
implementation detail of FileManager / FileEntry for the include path
logic to work), and instead hands the correct lookup information down to
LookupFile.
This will allow us to change the FileEntry's behavior regarding its Name
caching.

Reject virt-specifiers on friend declarations. Give anonymous bitfields a
location so their diagnostics have somewhere to point.
